If you had the skills to make a new game...
... and the resources, and a dev team to help you out, what kind of game should it be?
Personally, I'd make a new side-scrolling beat 'em up with the title: "Prügelspiel 9000!"
It would feature three selectable characters:
Hans: A giant Swarchenegger-type. Rediculusly aryan and dressed in lederhosen. The Sound of Music on steroids. Plays a bit like Max from SoR.
Heidi: Looks like she just came from a waitress job at the octoberfest. Equally blond and braindead as Hans and has a rack that makes you go: "...mommy". Her weapon of choice being a set of huge beer mugs.
Fritz: Skinny pale guy who has a lisp and smells funny. Fights dirty.
The gameplay would all be about beating the crap out of skinheads, nazi zombies (not very original, I know) and yetis. And everything would be stupidly stereotypically German. When you make your special move the characters yodel and you eat sauerkraut and knödel in order to regenerate your health. The game should also be bloody and gory in a way that would make Paul Robertson say: "That's sick, dude...".
Well.. I guess I'd just like some more side-scrolling beat 'em ups for the MegaDrive/Genesis :D
