On Facing Worlds

: I think it's hard to replicate correctly the feel of a game in a different engine, because it's not always about the weapons but it also involves the physics and many other things. It's already extremely hard to do so between games running under different versions of practically the same engine (UT → UT2k[x] → UT3), let alone between two games who share nothing in common, technically wise (UE[x] → IdTech[x]).
As a long time UT player I have seen tons of conversion mods and mutators from UT to UT2004 to UT3 or the inverse, and as far as I'm concerned, none of them managed to catch well that style.
