Let's do this thing.
I'm dividing my list into two categories, the first being games that're reasonably assured future purchases at this point unless they turn out to be unexpectedly shit, the second being games that've engaged my interest for one reason or another and that I'll be watching out for in future, but aren't yet prepared to commit to, mentally or otherwise. On with the show!
Likely Future Purchases
Guild Wars 2
Deus Ex: Human Revolution
Legend of Zelda: Skyward Sword (yeah, not PC, sorry)
Rock of Ages
Following with Interest
The Old Republic (my attitude towards this game vacillates between 'maybe if I look at it sideways...' and the kind of fascination involved in observing a derailing train)
Starcraft II: Heart of the Swarm
Alice: Madness Returns
Age of Empires Online
