Do a 3rd person shooter game where you are a ragdoll. I think that would be an interesting game and would actually make this myself if I wasn't busy with another project.
Okay, who are the judges? Also, do you know where to find a good explanation on how to make a 3d active ragdoll? Because I checked, and there aren't that many...
I think I might have a friend who can judge. also for the ragdoll thing, it's kind of built into unity when you are rigging something for animation. if you want a tutorial I can make one!
If you keep starting and abandoning games, then you don't need yet another idea for a game to start and abandon. You need to pick something you already started and finish it.
