I'm only really looking at Steam at the moment, but let's discuss anything you want.
Bought Evil Within for 66% off, hope it's good. Also got KoF98 pre-order as it's 20% off and I'd be buying it anyway.
I'm tempted by Rome 2 for 75% off, still not sure I want to pull the trigger... it's only $16 or so, but I don't know when I'll get a chance to actually play it through... I think I'll hold off. I have enough games to play.
EDIT: Rome 2 is only $11 on GMG... HNNNGGGGGGGG FUUUUUCK
EDIT 2: And Evil Within was only $16! I COULD HAVE SAVED A FURTHER $5! nooooooooooO!
