For me? It's undeniably Child of Eden... played it at a display case in a store on the 360, I liked what I saw and decided to rent in on the PS3 before deciding whether or not to buy it. It started off great but got really annoying when I realised I had to replay the first 2 levels over and over just so I could unlock the latter ones. Eventually I lost all interest I had in the game.

The visuals were nice but after seeing the same thing over and over again, the novelty wore off pretty quickly.

Socom 4... nuff said

NOA.

As much as I hate saying this, so far it has been Uncharted 3.

Crysis 2, it just wasnt all that. Mvs.C3, the online needed alot of work, I mean hell Capcom. Mvsc2 and SF3 had better matchmaking, and those are freaking DL games. Then they have the audacity to announce a cheaper version only a few months later?

lack of localization announcements for type 0 and vc3.

I'm going to have to agree with this, it was an amazing game, it just didn't blow Uncharted 2 out of the water like I expected it to, it let me down in a lot of ways.

I've got nothing else to list really, haven't played much this year.

Gears 3 campaign. It has its good points, but was overall very disappointing.

While still the best game I've played so far this year Killzone 3 let me down. The devs could and should have done a much better job, delay the game for all I care.
