Very difficult month to pick due to nostalgia and brand new games. Though for my money, I'll pick Dragon Age. I believe in it after seeing the many trailers.
The one I'm most interested in is the new Dragon Age. I absolutely loved Dragon Age: Origins and despite the second game being not so memorable, I've got faith that this one might be a return to the previous high standard. I'll probably pick up AC:U but as it stands, it's far from the most interesting. It's an interesting setting, but it'll be more of the same and I don't really see how any side activities could compare to Assassin's Creed IV: Pirate Simul- Black Flag.
OR/AS, no question. I'm already getting Smash for the 3DS and everything else is a bit meh. Although... why is Persona Q not on the list?
Although I am excited for Dragon Age: Inquisition, I'm also cautious about getting hyped. Dragon Age II was just...meh. Smash Bros and Pokemon are must-haves, but I have a version of the former and a taste of the latter.
