Steam have been running a sale with different games discounted every day. Current collection includes the original Final Fantasy VII. A classic game, although now showing its graphical age (this was during the time of the original PS1/PSOne/PSX console, and I played that game to death on my original brick/fat/phat PS2 — which I still have, mind you.) So take a look if you want.
