So, I was gonna recommend the Assassin's Creed series, but you have all but AC3 on Steam. The LEGO games are pretty spiffy on consoles, bit easier to play with a controller I've found. I also support the GOW series, I have all three as well. Forza Motorsport, but I wouldn't buy all four, just get #4 and be the happiest. That one tied in with Top Gear and has -epic- cars like the Veyron. They also have the Top Gear Test Track with minigames. 'Splosion Man is a cute game, but I don't play it often anymore (lost its appeal, and newer games are on the market better than it.) Stacking is a -wonderful- little game for when you're tired of blowing stuff up and shooting stuff and driving. I enjoyed it immensely. Everything else you listed is okay, but I have no experience with any of them beyond Halo, GOW, and Crackdown 1 (I was bored of it quickly to be honest, but I'm sure #2 is better.)
