Unfortunately I haven't been able to play as much as I'd like this week, but with the short amount of time with each game, here we go:
ACIV: 9/10
Most played game so far. This game looks amazing- and I was even impressed before the 1080p patch. Overall I just like this so much more than ACIII, even though I don't prefer the setting as much as past games.
Flower: 9/10
I played this game to 100% completion on the PS3. Replaying it has been fantastic... and the upscaled graphics and FPS really benefit the game. Just an overall beautiful experience- and I hope people playing it for the first time are enjoying it. I wish they could have added something new to this version (a snow level is something fans of Flower talked about back upon initial release), but since TGC wasn't responsible for this upgrade I didn't really have expectations for that, to be honest.
Killzone (single player): 8/10
Lovely looking game, wonderful art direction, but the story is kind of 'meh' so far. Didn't enjoy single player for KZ2, didn't bother with KZ3, but I'm enjoying this one. I have gotten killed a few times just examining the details in the scenery.

Haven't played MP yet, but I suck at MP FPS games, so I'll probably jump into a few games drunkenly this weekend.
Resogun: 8/10
This game takes me back to the 8 & 16bit days, but wow is it stunning to look at. I won't claim to be that good with twin-stick shooters, but I find myself picking up and playing this game a lot. Housemarque did a fabulous job.
Contrast: 8/10
Love the art direction and the overall pace of this game. Very clever in design and a wonderful freebee for +ers. Makes me want a new (good) City of Lost Children game really bad. I want more games like this. With Sony's dedication to indie developers this gen, I don't think I'll be disappointed.
Knack: 7.5/10
This game took a beating with reviewers, but I'm having a lot of fun with it. My daughter loves it, so I definitely need a second controller to co-op with her.

It can be a bit brutal at times and the overall art direction isn't really to my liking, but this game reminds me of something that would have been on the PS1 (not referencing graphics, of course).
Madden 25: 5/10
I expected this, but hotdamn is EA/Tiberon garbage with this franchise. I've managed to have some fun all things considered, but some of the glitches have changed the course of a game. In one instance I
clearly caught a pass, my receiver took about 5 steps before going out of bounds, had possession of the ball, and somehow it was called "Incomplete". It would not let me challenge it. Other than a few superstars (like Adrian Peterson), many of the players look like dogshit. Any white guy with long hair is laughably bad. MN's Brian Robison looks like he has blonde dreadlocks (he has a brunette ponytail IRL). Playing in 'Broadcast Mode' makes the game look a bit better, but yeah.
Still have yet to play BF4 and NFS:Rivals.
