Mini games? hmm, maybe some of these mini-ideas <img src="smileys/smiley17.gif" border="0" align="middle" /> No idea if these are already done before but here's a few games which focus on simple gameplay (not like WarioWare micro minigames, but rather games without huge AAA plots and dialogues):
-Small sim game, like a pet or plant life, kind of a zen/peaceful feel
-Folk exploration game, randomly generated towns/villages where you need to do small tasks for people in a village. Each time you complete a village it's stored to a canvas image and added to a square of a "map" made up of every village they helped in that session (so make villages start easy to progress through). Should leave the player feeling happier at the end of the game.
-BrainBrawn, solve algebra and logic puzzles in a turn-based fighting game (multiplayer? Fastest answer hits first, easier questions for defense moves?)
-Trader, a game set where you deliver items through time. Initially trading by foot then wagon, car, plane, shuttle, spaceship where the scope of the game expands to about the size of a galaxy
-Helper, a platformer game which initially has you making levels harder for an AI to beat until they can't beat any of them, secret twist where you're in the future and making a challenge for yourself. Player beats all the levels in reverse at start to make them difficult, then they must beat the level themselves going forward in time to become the next "helper". Kind of an idea of "self improvement"
Ill stop before I get too crazy with ideas I guess, the names are just to give some image to the mock ideas, but hopefully these at least give some ideas to people <img src="smileys/smiley1.gif" border="0" align="middle" />
