So, after playing some Carnival Games for the Wii just now, I realize that a putt-putt, aka miniature golf, WiiWare game would be totally friggin' awesome.
In Carnival Games, there is one game where you get a single chance to sink a putt, which is lame, but semi-cool in the super putt game. Anyways, it makes you realize how awesome a full fledged game would be. The putting would have to be more defined than what Carnival Game has, and to make it long lasting, there would have to be at least 2 or 3 different 18 hole courses, but adding in some multiplayer and cool holes with wicked obstacles and such...it could make for a good time, and such a game wouldn't be too terribly difficult to make...at all. There really isn't too much in the way of graphics that has to be done. You just need to get the physics down, which also shouldn't be hard...just a ball rolling and bouncing off walls.
It could be killer. That, and a disc golf game. I want.
