If you’re after more Oddworld goodness, the entire series is currently 80% off on the Steam store:
Oddworld: New ‘n’ Tasty – $3.99
Oddworld: Stranger’s Wrath HD – $1.99
Oddworld: Munch’s Oddysee – $0.99
Oddworld: Abe’s Exoddus – $0.59
Honestly, I can’t see too many reasons not to install this, even if you don’t feel like playing right now. The game is a classic and one that you’ll be sure to feel like playing at some point in the future.
