Mass Effect 3 (360)
While I'm loving it, I must admit the animation looks bit stiff - and people looks more weird, somehow. Like more so than ME1&2. Maybe I didn't realise it when playing ME1&2...
Still, loving it - and the multiplayer is really fun too.
Mario Kart 7 (3DS)
Purely for multiplayer/Time Trials. At times it is pretty much weakest MK game, but it does better than Wii one (minus 8-players online instead of 12) so I'm happy enough. It may not be MKDS, but could be considered sequel to MKDS.
Dead Rising 2: Off The Record (PC)
The little improvements have actually improved DR2 - I liked DR2, and I even like it better, thanks to checkpoint system. The survivors seem dumbed down (they were much better in original DR2) but not bad as DR1, and if they died at least I have checkpoint to try keep them alive again, rather than re-loading old save.
