Originally i was going to take the top five from the qualifier only, but considering there was s three-way tie for fifth place between Portal2-Bastion-Batman:Arkham City, i thought i'd just throw them all in.
Skyward Sword, then Dark Souls, then Catherine, then Bastion. I like them best because they are very unique and innovative.
Skyrim, Batman, both are great, but they have happened before. Nothing new to their respective genres.
It was a slightly tough one. Decided to go with Skryim in the end, definitely a great game that absorbed many hours of my life :).
But a lot of fun games Catherine (good story and pressure tower climbing), Batman (love beating up various thugs), Zelda (it's Zelda), etc. Great year for gaming.
