I love all the Oddworld games, but not even Stranger's Wrath can beat Abe's Exoddus, in my opinion. So I went with AE. (Man, how I miss the quintology.
) SW is very fun to play and was a very enjoyable experience for me, but it doesn't take near as much wit and skill to play as AO and AE does (which got me into Oddworld in the first place).
