This year for me, is a bit like last year. Taken by itself this is actually a pretty bad year if you asked me, and yes from this year there wouldn't be much that would stick with me over time. In reality though I played of stuff from 2007 this year because of a renewing interest in console games.
From the poll I played Fallout 3, Grand Theft Auto IV, Mario Kart Wii and a bit of Super Smash Bros Brawl. Fallout 3 was quite the game, a near endless world with a near endless storyline. At that point in time though, such a game was too big for me, and I lost interest at some point. I have seen the end though because my mother did play it all the way through. At a family friend's house I came into contact with GTAIV. It was at least 2009 however by this point. I remembered I liked the simpler first two games in the series from years earlier, and I wanted to get into this one. However after I got it and played with it myself I was let down quite severely. I felt it was utterly boring. Because you "can do anything", you're actually doing nothing. In addition I didn't like the characters or felt interested in the scripted events of the storyline. I dropped the game quite quickly. On Wii, which by now got more and more playtime, I got Smash and of course Mario Kart. The latter cannibalised the former heavily. I had played the N64 Smash and liked it, but I never really played much of Brawl. This is because of Mario Kart Wii, which I liked very much. I felt it was an obvious step above the to me disappointing Double Dash and I like most of the tracks, the mechanics and the new bikes which added an extra layer of strategy.
From the 'other' list I played Professor Layton and the Unwound Future, Guitar Hero World Tour and SoulCalibur IV. SoulCalibur IV was nice, but it wouldn't replicate the times I had with family and friends during the original SoulCalibur days. It couldn't really, the multiplayer sessions were over. Professor Layton was also good, I had fun with it, but the novelty was gone because it wasn't the first game I played in the series anymore. Then Guitar Hero World Tour, which I played a lot. I was like Guitar Hero III, but with other songs, so that was great. I was easier though, and songs would be simpler. Though, with III they went overboard with the amount of notes that actually played on some songs.
This year doesn't really have a standout for me, I'd say in itself an indicator of the year's quality in my experience, but because of the amount of playtime it got, and because nothing else clearly beats it, my vote is for 'Other', with Guitar Hero World Tour.
