Wow this post has been a while. Yes, multiplayer with this is pretty good, and I have it installed on both Windows and Linux PCs. Online servers for it are usually dead, however. You'd have to host your own with bots or get some friends in to actually play. For singleplayer Doom, I prefer using Woof! Or DSDA-Doom. For other multiplayer ports, there's ZDaemon and Zandronum.
Burnout 3 absolutely. Paradise was a great game but it's format shift to open world effectively killed the series. Also made races really repetitive since they always went to the same places and you didn't have an incentive to explore the rest of the map, which was full of really cool stuff like the quarry and train lines...
Anyway Burnout 3 is just the perfection of the classic formula. Shoutouts to Revenge for the traffic check mechanic and the cool new car designs.
