My opinions
Best console game: Mario Kart 7 on 3DS (just ahead of killzone 3 on the PS3!)
Improved upon the N64 version with better balancing, the cpu players actually use boxes properly instead of randomly getting items to use and the online multiplayer is flawless. The ghost data via streetpass constantly gives me new track records to beat from around the world and the unlocks add something new to the mix. All in all its still the insanely addictive game pretty much anyone can play after an entire 10 seconds of playing it!
Best single player PC game = Skyrim
The scale of the game, the overall graphical approach to it, narrative, music and replayability are all staggeringly good. It improves upon the previous elder scrolls games by finally making archery and magic as easy to use as hack and slash gameplay. Coupled with the none scripted dragon fights which are overall very impressive to the sheer randomness of the game where you can have NPCs turn on you because you accidentally walked into the table and knocked a drink over, just adds to how insanely well made the game really is.
Best multiplayer game on PC = Dungeon defenders
Big change for me here as I only usually view AAA rated games as GOTY worthy, which is a very naive, yet honest view lol. This however is one of the rare titles which is stupidly good on coop and is insanely addictive to boot due to the RPG element to it. Overall a very well thought out game and has a pretty good amount of content. This is the one and only title I WILL be buying DLC for in the months to come.
Worst game this year for me? Brink
Spent £25 on this expecting it to bring something new and unique to the table and really be fun to boot. Turned out to be an extremely dumbed down console game which had a decent idea, yet utterly pathetic execution.
