Pinball Arcade is cool if you like pinball, but can get expensive. You get one free table to play, but it's all officially licenced 3D tables based on real pinball games. So to get more tables (and there's tons, plus adding more as they can) will mean shelling out some cash. I think they said their goal is to virtualize most every real table.
I've also started playing one called Smash Bandit Racing. Basically you have to outrun the cops while destroying as much of the city as you can. The camera angle looks as if from a t.v. helicopter, and you hear the news caster giving a pseudo play by play. Her vocabulary is limited, so it gets a little tiring hearing her say the same things all the time, but it's not too distracting. You control your car with a single finger for steering/gas, so it's real easy to play. I also have their other game Smash Cops Heat. It looks like the same type of game, only you're now the police. I'm waiting to finish the other one before starting the cop version.
