While I plan to play this version through myself, it's actually inferior to the PS2 version in several ways:

PS2 version has scopes that you can see through on the Tau weapons, these are blank on PC.

The sword isn't properly alligned with Kai's hand.

That one floating door Mandlore Gaming encountered isn't on PS2.

Menus and visuals generally seem downgraded.

While I've yet to do a full playthough, it appears the PC version of Fire Warrior was based on an early build so it lacks alot of detail that must have been included last-minute on the PS2 version.

Yeah, but unless you have a working PS2 and an old TV, plus a PS2 copy of this game, then you have no other options. Emulating this game on PCSX2 is impossible due to crippling performance issues that happen a couple of levels in.

PC version is fine, and with these new improvements it's damn near perfect as long as you use a controller. I can get over not having some minor gun lens effect that has zero impact on the rest of the experience and serves no benefit to the gameplay.
