Indeed Max, that is the anwer to the question why it DIDN'T appear on PS2. But the question was, why it COULDN'T. And the answer to that, is that it certainly COULD have been on PS2, but it didn't. It is a shame, because on the day I wanted to buy a ps2 (one day BEFORE official launch day in Europe) I read in a magazine that Oddworld became XBOX exclusive!!!!.
No second thoughts, I bought that ps2 anyway, but it did cost me also to buy an XBOX. And boy, I didn't use that thing much
. All heart and soul for Oddworld (my first ever demo I played on the PSX).
