A fair few, though mostly in sales if the price is too good to resist, though my backlog is so huge at this point that I doubt I'll get through it anytime soon.
As for brand new games, very few these days. This year, the only new releases I've bought are Shadowrun Returns and Dragonfall, Divinity:OS, JULIA: Among the Stars, Wasteland 2 and The Sims 4. In November I'll buy Dragon Age:Inquisition, and that's it for 2014.
My only guaranteed buys for next year are Batman: Arkham Knight, Eternity (already paid for through Kickstarter), Torment and Dead State if they come out next year and TW3 - though I'll be giving birth in February, so I'm not sure I'll be getting it Day One!
