Well, I'll let Max cope with all the cartoon-like imperfections. He's so good at it
As for Stranger, Lorne saw how much of a disapointment MO was and acknowledges his mistakes. He won't make the same mistakes again, that's why he's aiming for every chance he gets to have more working time with Stranger and shape it into his vision perfectly. Stranger won't turn into another MO, it's far from it in many ways. According to Abe Babe, it's very different from the Oddworld we know but shows that only Oddworld could craft such a game.
