Earlier quoted context omitted.
> But they all should look like Big Boss then? Not quite, because they were not all direct clones the way we think of cloning in real life, because in the Metal Gear universe, they could do "selective cloning". I forgot the details of how exactly they described it (and I haven't played beyond MGS3 yet). But in MGS, Liquid and Solid have a conversation about it, where Liquid insinuates that they took the "best genes"…
Actually, Solid being the better clone and Liquid being inferior is unreliable narration on Liquid’s part. He was led to believe so, but Revolver Ocelot contradicts him later on. Revolver Ocelot: "Yes. The inferior one was the winner after all. ...That's right. Until the very end, Liquid thought he was the inferior one."
Inbefore someone says "it is an old game", I beat MGS 1+2 just a couple years ago for the first time ever, and I usually am more into newer games. Still looking forward to play MGS3 and the rest of the series in the future.
