Don't do it
Doesn't it feel like this Steam Summer Sale's been going on forever? Are you bored yet? Hope not. Boredom's the first step on the road to relapse. Hopefully you have a good friend to blast "Goodbye Horses" through a boombox so you don't slip and spend any money.
The Flash Sales for the next eight hours are The Secret World ($11.99), Next Car Game ($17.99), Infested Planet ($7.49), and The Testament of Sherlock Holmes ($3.99). Platformers with female protagonists won the Community Choice vote, so those titles are Mirror's Edge ($4.99), Tomb Raider ($4.99), They Bleed Pixels ($1.99), and Giana Sisters: Twisted Dreams ($2.99).
