Doom 3: BFG Edition (50% Off)
Price: $14.99 (50% Off)
Doom 3 kinda sucked when it came out, but id Software and Bethesda felt it needed another chance on modern computers and so BFG Edition was born. With enhanced graphics and a few gameplay tweaks (no more off-handing the flashlight!) it's a much better game and suggests that history could have been a lot kinder to Doom 3 had they got it right the first time.
