I got my $50 Steam gift card the other day, and I did manage to get Peggle Deluxe and Atari Vault for a total of $11.23 because the Steam Summer Sale is going on.
I tested those games out and they both worked fine. 😀 I was thinking about getting the entire Arcade Game Series pack that has Pac-Man, Galaga, Ms. Pac-Man and Dig Dug, but I decided to wait for their prices to drop down.
