I recently just came back after 3 or 4 years and yeah, in terms of gameplay - better add ons (nice tree bricks / doors / bots), better servers (loads more variety - jail escape, boss battles and racing). Awesome in-game rendering. Maps are gone, RTB is gone, hardly any familiar faces from the starting days. RTB add-ons are mirrored in places.. aaand last but not least, it's still fun :D
