Space Harrier (Sega Master System, 1 player, 500 Wii Points) is one of the last of a dying breed: Beloved classic action franchises that haven't been given a completely unnecessary modern remake (and no, we're not counting Planet Harriers). But the closest you're going to come, a Virtual Console release, will be available at noon EST today.
Buy it, not just because it's fun, but because when that unnecessary remake does come, you'll be able to say it's inferior to the original like a champ.
