Summary: First of let me caution make sure you first can download and get working a GamesForWindowsLive account! - I had to create a whole new email address an other carp because had one that was defunct, that took a day to figure out...

Summary: It would be pretty damn awesome if my Macbook Pro 13" 2011 could handle it. I still play it, though. Sure it lags sometimes when it eat all my memory, but it's still a pretty damn good game. I still recommend it on Macbook Pros and I definitely recommend it on Computers that can handle this awesome game.
Summary: Great game, excellent graphics, keeps my 9-yr old entertained, albeit some of the language is not appropriate for that age. Requires good graphics card or game stutters. Downside = Steam, would give 5 if it weren't for that.
Summary: Wow. What a beautiful amazing game! The gameplay is so flawless that you actually can feel like Batman running around a fully developed section of Gotham City. So far, the plot has been wonderful. So far, the art is unparalleled. I'm docking one star because of the profanity. The profanity that is there is stuff you'll hear on normal TV nowadays. Maybe less than PG rated, I don't know. Personally, I don't need it.
Summary: the game stack at the beginning because I have windows 8 and win 8 don't run windows live game for windows. but.... the 3d graphics works amazing. I bout this game because I love this game and I finished the last one.
