Scplinter Cell is indeed using unreal 2.5. Vegas however was always UE3 based since the very beggining.

Wow I called my friend and I wasn't wrong, the Ubi Producer really told us that (last May 2007), Ubi never had the UE3.
So he was probably wrong afterall and we got (17 students) got screwed up lol. I love the Ubisoft Campus....
UE3 for the win, 2.5 for Splinter Cell Series so EndWar should use an original UE3 as his base.
But I definately think buying UE3 wasn't the best move, but it can't be that bad.

It's just sad that the game didn't came out with the Editor, now you got two proofs for one.
Vegas on UE3 and Splinter Cell: Conviction on 2.5.
