I have been thinking about game length lately and how it affects playability. I am speaking of more than just player preference. I think length exaggerates certain types of problems in game design so a small problem in a short game becomes a large one in a long game.
Here are a few design problems that might get under the wire in a short game but become a huge problem in a long game.
Player elimination: If you get knocked out of a 20 min game half way through its no big deal. In a two hour game it is.
Run away leader (Living Death): Much like the player elimination but you can’t go do something else since your still in the game. You are forced to keep playing without any hope of winning.
Down time: This one is at it worse when you have large number of players and a fairly simple decision to make in-between turns, a game that doesn’t keep you busy thinking or interacting becomes dull quickly exaggerated by a long game time makes down time a game killer.
What other problems do you think game length plays a part in?
