Yeah but the idea for this Jam didn't seem to be that one. It was gonna be one of the 4 themes that are on the main page, you're just trying to do something completely different. The idea was to have the four generic themes up for voting and one would be chosen and we would have to make games using that generic theme. Not a consistent theme like you said. This is not Ludum Dare. If you want consistent themes, suggest the idea WEEKS PRIOR to the jam. Not one day.
I mean, isn't that kinda silly? Oh, so the theme will be Wild west, you have one month to make mockups and think about ideas. Then one day before the jam, you say "oh so the wild west theme will be "Aliens and Cowboys. Must have aliens in the game" " Well, there goes my idea for a game without aliens that I've been writing for a whole month just because someone just decided that the theme should be less general. That just makes more people upset and not want to participate in the jam because it cuts creativity, you know? The palette is already a challenge, why do you want to complicate people's lives even more?
