The Oddworld series Steam forums are still filled with threads about how often they crash/how poorly they run. I really want to pick them up at that price but it seems like a lot of people are still having trouble even getting them to run.

Was just about to ask about this. That's a shame, $2.50/$3.75 is a great price, but not for a broken game.
