Wiimote prototypes...

[A Black Falcon]

You should recheck your "most, a few" statements. The PS1 started with the 10 button but it was replaced by massive margin to the point where the second type outnumbered the first. So it would be more accurate to say "first, 10, later 12", also you should label the analog stick number .

I was just talking about buttons USED. Just like the Sega Genesis, while lots of people do have the later-model controller (6-button for Genesis, 12-button for PSX), most games only use the basic controller's buttons. For the Genesis, pretty much only fighting games and a few sims and stuff use the six button controller. For the PSX lots of games support rumble and analog controls, but only a very, very few actually REQUIRE them, and the only way that a game can use the last two buttons is to require analog since the analog-click buttons are new... so I think my "most 10, a few 12" is quite accurate. If we were talking rumble or analog stick use things would be different, but I wasn't.
