AE of course. Bigger adventure. you learn more about Abe, and he speak less retarded than in AO.

Rhyming makes one retarded?
I'd label your views as discarded
Not once in AE
Is he such a cutey
As back in AO when he barded.

haha, i love this question but i love some of these replies that bit more :P some people dont realise that some posts are only jokes! but to answer the question...i dont really know :/ exodus is probably a better game to play through where its a bit trickier and has more going on...but oddysee....its just as classic so i would have to say them both!!! sorry for not giving a real answer :P

yeah what the deal with abe's voice in Oddysee!

I must be totally honest and say that I cannot choose between Abe's Oddysee and Abe's Exoddus. After years of having them both in my possession, I still cannot decide which one I like best.

Sure, AE is the sequel and has smoother rendering and gameplay, but AO is a classic game and cannot be beaten. So, I honestly think they are both the best.
