star wars the old republic
max payne 3
I was a beta tester for SW: the old republic and I must say it's the most impressive Star Wars game I have ever played. It was only for the weekend, but I'm guessing you could play several months and still be busy with all the story lines. Tried both Jedi and Sith and both sides had good stuff. Did not have the time to play as a soldier, smuggler, bounty hunter, etc.
Too bad they ask for a monthly (or two, or six montly) fee, if not I'd buy it instantly. I can't bring myself to paying every month knowing I won't have time to play it daily.
