@monorail I've.. .played like, two of them to completion,, and a bit of one of the earlier ones. 3 was the one I had the most fun with. 4 was... just 3 but with a campaign pack. This was brought into even starker relief when one of the DLCs for 3 has elements that are actually in the core game of 4, meaning that instead of doing a full DLC campaign for 3, they just split it off into a full price game which uses the same assets and engine for the most part. :/
@monorail the other one I played was 2 but getting that to run at anything approaching playable is a nightmare, or... well... WAS a nightmare, I dunno if newer versions of it are any better tbqh. Either way it stopped me enjoying it because the cars all handled like icecubes and the framerate was atrocious.
