Projectsonic: Usually I'm not for the freemium stuff, but The Pinball Arcade would probably find an interesting home here as it's all detailed recreations of real pinball tables. Costs a couple arms, legs, and your liver for the whole thing. But it's usually worth it if you just buy a season at a time or whatever.

The chances of it making here are nil though as it's mostly Steam, mobile, and whatever consoles there are. It also makes use of things Galaxy doesn't have yet.
