Don't know if this has been done or not, but what new types of games would you like to see come out? Or what fundamental improvements would you like to see made to current games?

i would love to see a FPS that incorperates skill points in a meaningful and challenging way. The first ghost recon came close to what i have in mind, but i want to see more of a reward system for getting headshots and high kill ratios.

What do you guys think?
