1: LA Noire. good game, however, it has lots of downtime. you can skip the long driving sesssions that dont do much but provide banter and insights into the characters. the investigations are fun, as are the interrogations, but the side quests are cheesy, and not much fun. i'd give it an 8/10.
2: ME2, i've played this series only on the 360, when i had one anyway, but i gotta say, it's a bit overrated. the choices never have any weight outside of which romantic relationships you want to pursue, your party is interchangeable, with no real wrong way to go about it(except for the player specific missions), and it all comes down to a TPS with a dialogue tree. 8/10 for me.
3: killzone 3. the campaign was awesome, multiplayer has become more like the CoD's of the world, and less like killzone, but it's still a blast. 8.5/10
4: infam 2: if you played the first, and enjoyed it, this is a must buy. sucker punch really went above and beyond with this one, from the use of trophies to unlock special abilities from the get go, to the user generated content, infam 2 is a homerun. 9/10
5: dead island. i'm definitely going to rent it, but i'm not sure whether it's goingto be a great game or not. just don't know enough yet.
6: i'm a resistance fan, so 3 will be a day 1 purchase for me. the beta has been fun, if not problematic, but it's a beta. and i get the sense, that the campaign(which once again features 2 player co-op) will be the most epic of all the FPS' dropping this fall.
7: dead rising 2.never played it, never wanted to. but it's cheap now.
but you are leaving out, arguably, the most important title in the PS3's line-up this year: uncharted 3.
