Star Wars Arcade: Falcon Gunner
Did a search on the forum about this game and got no hits. I downloaded this last week and highly recommend it. I did Google searches and all of the hits were in November either 2010 or 2011, which is weird; I can't tell when the game actually came out.
I'm only a few levels in but you're basically manning a rotating laser and blasting ships and asteriods in a 360 radius. There's a few ways to go about it, including a setting in which you can spin in an office chair and the scene shifts accordingly. Pretty awesome and addictive.
