I would like to see as the last game from OWI providing the technology is there, a game where you can go anywhere on Oddworld. I personally would love to virtually climb those mountains.

Well to the actual point I don’t think we will see anymore of the meeches because of the points already made but I do believe we will find out more about them actually in one of the games.

Lorne has said we will get to see the Meeches at some point, but never specified whether it would be due to a flashback or species revival. Gabbits have been brought back from the brink of extinction, so doing the same with Meeches would be rather samey, unless it brought up issues of cloning and genetic fiddling, like in the Freezer image.

We've also seen underground parts in all three Oddworld games so far, if you count Monsaic Lines as being underground. The light levels are high, but then they are called Monsaic Caves (somewhere).
