When a Second Copy of a Board Game Is Worth It

The One Copy Rule is simple: a play group needs one copy of a game, not one per person. But every simple rule has edges, and this is where people get stuck. Is a second copy of a board game ever worth buying? Yes. Sometimes it is the smartest purchase on your list.

This article is part of The Shared Shelf series from The Ludarium, and it exists to draw the line clearly. We will walk through the one test that decides every case, apply it to each common exception, give you a checklist, and then be just as clear about when a second copy is a mistake dressed up as a reason.

If you have not read the pillar yet, start with The One Copy Rule. This piece assumes you buy the basic idea and want to know where it bends.

What is the second-copy test?

Every exception below comes down to one question:

Does the second copy create plays that would not otherwise happen?

Not “would it be convenient.” Not “do I like owning it.” Plays. Actual sessions at an actual table that the first copy, sitting where it sits, could not produce.

The reason this is the right test comes from cost per play: price ÷ plays ÷ players ÷ hours. A copy’s cost gets divided by every person it serves. One copy of a $40 game played twenty times by four people is about fifty cents per player per play. A second copy that produces no new plays doubles the group’s cost and leaves the numerator of fun exactly where it was. A second copy that produces its own twenty plays is just a second good deal.

So the test is not a loophole. It is the rule, applied with care.

Which exceptions pass the second-copy test?

Here are the cases that usually pass, with the test applied to each one.

Two separate play groups

You have a Thursday group near home and a family group you see on holidays. Those are two Shared Shelves with almost no overlap in players. A copy of Ticket to Ride that lives in each place will be played in each place. The first copy, two hours away, cannot serve the second group.

Test result: passes, as long as both groups will actually play it. If the second group would play it once a year, a cheaper option is to bring the first copy when you visit.

A home or family copy

The group’s copy of Azul lives at a friend’s apartment. Your kids, your partner, or your roommate want to play it on a weeknight. Those are plays the group copy will never produce, because it is not in your house when you want it.

Test result: passes if the home plays are real. Be honest about this one. “My partner would love it” is a prediction. “We played it four times at Dana’s and my partner asked when we could get one” is evidence.

Games that improve with two sets

A small number of games are designed so that combining copies makes a bigger or better game. Two Dominion sets give a group a much larger card pool and let two tables run different kingdoms at once. A Magic Cube seats eight drafters, so a community with sixteen regulars needs a second Cube to run two pods on the same night.

Test result: passes cleanly, because the second copy directly adds plays (a second table) or depth that the single copy cannot provide.

The always-needed anchor

Some groups have one game that comes out every session. It is the opener while people arrive or the closer when energy is fading. If the owner misses a night, the group feels it. A second copy of that anchor, kept by a different member, is insurance for availability.

Test result: passes only if missing the game means missing the play. If the group would just reach for the next game on the shelf, it fails. Run this one twice before buying.

Cheap fillers

Love Letter, Sushi Go!, Jaipur: games in the $12 to $20 range that fit in a coat pocket. Owning your own means it is in your bag at the café, on the trip, at the family dinner. The dollars at risk are small and the game shows up in more places.

Test result: usually passes on the strength of portability, but set a price ceiling. Fillers are cheap. A $45 game is not a filler, no matter how short it plays.

When should you NOT buy a second copy?

The exceptions above are real. These reasons sound like them but are not.

• “I want it on my shelf.” That is a collecting urge, not a play need. It is fine to collect, but call it that and do not count it as a group purchase.
• “In case they stop coming.” If a member leaves, the group buys one replacement then. Buying insurance copies against every possible departure is how a closet fills with shrink-wrapped Catan.
• “I might start a second group.” When the second group exists and has met twice, buy the copy. Until then, it is a game on the Shelf of Shame with a good story attached.
• “It was on sale.” A discount on a duplicate is still a duplicate. The same sale price buys a different game your group does not own.
• “I want the newer edition.” If the group’s copy plays fine, a newer printing adds no plays. If the group’s copy is falling apart, that is a replacement, not a second copy, and the old one should leave.
• “The owner never brings it.” This is a social problem, not a shelf problem. Ask them to bring it, or ask to borrow it for a month. The fix is in The Shared Shelf Social Contract, not at the checkout.

A decision checklist for second copies

Run through this before you buy. If you cannot check at least one of the first five, do not buy.

1. Will it be played by a different set of people than the first copy? (Separate group, family, roommates.)
2. Will it be played in a place the first copy cannot reasonably reach? (Home on weeknights, a distant city.)
3. Does combining two copies make a bigger or better game? (Dominion, a second Cube.)
4. Is this the anchor whose absence actually cancels a play? (Not just “we’d miss it.”)
5. Is it cheap enough and portable enough that having it in your bag creates plays? (Set your own ceiling; $20 is a common one.)
6. Have you checked the pooled group shelf first? If your group has not pooled shelves yet, How to Audit Your Group’s Game Shelf has a template.
7. Would the same dollars buy a game the group does not own that fills an empty role? If yes, the empty role usually wins.
8. Can you name the next three plays this copy will get, with real people and real dates? If you cannot, wait.

The last question is the one that does the most work. A second copy that passes the test comes with a schedule attached. A second copy that fails comes with a feeling attached.

How does this fit into a Shared Shelf?

The point of all this is not to stop you buying games. It is to make sure every dollar your group spends adds something to the library that was not there before. Most of the time that means a new title in a role nobody has covered, which is why groups that coordinate end up with a far bigger shelf for the same money. Claim a Lane shows how four people divide that work on purpose.

Occasionally it means a second copy, because a second copy, in the right situation, is a new library all by itself. A home copy serves a family. A second Cube seats eight more drafters. Two Dominion sets open a second table. Those purchases pass the test because they pass the math.

One copy for the group. A second copy only when it creates its own plays. That is the whole policy.

The game is the reason. The people are the point.

FAQ

Should I buy my own copy of a board game my friend already owns?

Only if your copy will be played somewhere your friend’s copy cannot reach: a second play group, family at home, or a trip. If you only play that game with the friend who owns it, a second copy adds cost without adding a single play. Spend the money on a game your group does not have yet.

Are there board games that are better with two copies?

Yes, a few. Two Dominion sets give a bigger card pool and let two tables play different setups at once. A Magic: The Gathering Cube seats eight drafters, so a larger community needs a second Cube to run two pods. For most games, though, a second copy adds nothing because the same players cannot play both at once.

Is it worth buying a cheap filler game I already play at game night?

Often, yes. Short card games in the $12 to $20 range, like Love Letter or Sushi Go!, are portable enough that owning one puts it in your bag for cafés, trips, and family visits. The dollars at stake are small and the extra plays are real. Set a price ceiling so “filler” does not stretch to $40 games.

What is the second-copy test for board games?

The second-copy test asks one question: does the second copy create plays that would not otherwise happen? If it will be played by different people, in a different place, or as part of a bigger combined game, it passes. If the same four people would play it the same amount either way, it fails and the money belongs elsewhere.
