Finally decided to blow what was left in my Steam wallet:
F.E.A.R. + Extraction Point and Perseus Mandate DLC
F.E.A.R. 2: Project Origin + DLC
Brothers - A Tale of Two Sons
Night of The Rabbit
The F.E.A.R. games I already had a disc copy of but felt it was time to get a no disc version so I don't have to hunt it down whenever I want to play it. The other two games really took my fancy and I've been eyeing them for a while now. Besides, even if they're not that great, at their current price, it's not a major loss.
