My game of the year is none other than Metal Gear Solid 4 big surprise eh :P no other game in my list came close. Playing MGS4 has been the most fun I had this year, when it first came out I completed it 5 times nonstop that's how much I enjoyed it. Sadly it was the last chapter in Solid Snake epic tale but I'm looking forward to a fresh new start for the series, hopefully there will be some news about MGS5 next year.
I guess its time to update my most anticipated games list..here are some:
Killzone 2
Resident Evil 5, not too excited about this one yet but I loved RE4 so it should be just as awesome, the addition of co-op is sweet.
White Knight Chronicles, I hope it does well.
Uncharted 2, haven't played the first uncharted but I have heard many good things about it (still waiting for a darn price drop) :P
God of War III, It will be badass! I think I'm becoming a fan of the series. Teaser vid on Spike tv VG awards this Sunday. :)
oh and FF13 err forgot about it :? (edit: 2 trailers appeared today, it looks so good)
also Home just became public beta, don't really care about it in its current stage but it definitely has potential, I will just keep waiting until they add something worth checking out.
