NFS 3/4/5/Hot pursuit 2 were very different games depending on the platform.
I think NFS 1 and 2 too but I never played multiple versions of those.
NFS3 and 4 were curious because there was no definitive version. The PC version had generally more content, cleaner environments, longer career modes and higher framerate and also a cockpit view - whereas the PS1 version had better car models and better, more realistic driving physics.
with NFS 4 the difference was even bigger because the PC version actually had all the tracks from NFS 3 in it, and had much, much better damage modeling but the PS1 version had more music and the driving model was just so much more damn enjoyable. Also, some of the car models of the PC version are really really awful like the BMW Z3, whereas the PS1 version has some of the best car models of the console, especially when you consider how detailed the interiors are (GT didnt have interior detail in the PS1 era)
NFS 5, the PS1 version was arcadey as hell, still a good game mind you, but you could trash cars around like they were matchboxes.
The PC version of NFS 5 is one of the best simcades ever made imo, even to this day. The physics could not be any more different. These games didn't even share tracks, all the track layouts were different, the PC version had far more point to point races whereas the PS1 version had more circuits. The factory driver mode existed in both versions but had completely different objectives in general, which was funny.
Hot Pursuit 2 is a funny one because unlike in other cases, most people don't actually realize how different the PS2 version is from the rest. The PS2 version is the best one, by far, and the other versions (PC, GC, Xbox) are while still a fun game, is clearly inferior. Considerably worse career structure, worse driving model, way less exciting track design.
