In the last 12 months, I purchased UMvC3 at release, a new graphics card for SWTOR, 2 copies of SWTOR, 2 copies of Diablo 3, 2 copies of Guild Wars 2, and 2 copies of Mists of Pandaria.
UMvC3 hasn't even gone into the console yet.
SWTOR I'd rather not even talk about, though F2P will put it briefly back on my radar.
The friend I bought Diablo to play with raced to max level in a week and quit before the weekend we were going to start. We've played it about 5 hours total.
The lady of the house couldn't get into GW2, but she sure tried. I can't stick with MMOs without friends and family to play with though.
Part of me feels like every design decision but the environmental art in MoP was done by a spare team at Blizzard with no real supervision. That said, it's the only thing we're actually playing.
Important lessons learned and applied. I've compensated for most of this by dodging about 7 other bullets this year. Still mostly embarrassing though.
