The thing I can't decide on is how many buttons I should have for each controller. From what I gather 6 buttons are minimum for fighter games right? How about those 4 way games, are 3-4 buttons enough...too much? I know I don't want 7 buttons on the ends, and to be honest I don't want 6 unless they are absolutely needed for most games.
I guess I just need some advice from your experiences. Thanks group.
I think you want six on the ends for fighter games.
Question 1 is - for alternating 8-way games (Gyruss, Timepilot, I assume you intend to use the end joystick?) (I will assume so)
For the 4-way - the next question is "Would I be comfortable using some of the other players buttons for these games?".
If so, you don't need any buttons.
If not, it's a rapid case of diminishing returns -
0 buttons - Pacman series, others
1 button - DonkeyKong series,Galaga,Galaxian. (lots of 8-way games, but I won't include them).
2 buttons - don't really know of any, there probably were 1 or 2, lots of alternating 8-way games, but . . .)
3 buttons - only ones I know of were 8-way
4 buttons - probably too many
