Oddworld: Stranger's Wrath. Departing from the regular Oddworld expectations, Stranger's Wrath is a hybrid of third-person action and first-person shooter, seasoned with elements of the Spaghetti Western and Oddworld touches like the "live" critter ammo. The game is available now on GOG for $9.99.
If you'd prefer a sweeping adventure, The Longest Journey is on sale for $3.99. Much like The Neverending Story, we can't vouch for the accuracy of game's title, but it does involve a very long journey, so you'll definitely get your money's worth in this classic point-and-click adventure.
