i have some questions,
what the max amount of buttons needed for a 3-4 player game?
is 3 each correct?? ie xmen?
or are there any games that need 4 buttons per person??
Yup, there are a few that use 4 buttons. Dungeons and Dragons: Shadow over Mystara and Tower of Doom is a 4-button game. Awesome game for 4 players too, especially when you work together as the different classes.
I think the Knights of Valour series are also 4 button games.
IMO, you don't need to have 6 buttons for players 3 and 4 on your 4 player panel.
