It's still a great conversion. Very impressive what the original Xbox was able to do.
People that never played it decided later on that the frame rate was horrible, but as someone that did play through it, I didn't think so. Wasn't silky smooth at all times, but ran well and never turned into a slideshow. Half-Life 2 on the Orange Box for the 360 also had a frame rate with a lot of variance in it, but never got criticized for it.
You won't catch me saying this much, but this old IGN review nailed it.https://www.ign.com/articles/2005/11/12 ... e-2?page=1
Too bad revisionists have now declared that this was a bad port when in actuality it was perhaps the crowning achievement of the original Xbox, albeit a year too late to generate the fanfare it deserved.
