After all these years this game is still great. A slower paced iteration of Doom that still divides fans to this day and while it wasn't what I wanted Doom 3 to be all them years ago it's still worth playing and it's the version I'd recommend playing over the BFG re-release which changes the flow of the game with the amount of health and ammo pickups making it a far easier game.

In terms of getting it running I'd just download this source port: https://dhewm3.org/ and all you have to do is literally drag and drop the files to the files to the Doom 3 instillation and you're sorted. The source port also gives you the EAX sound effects regardless if you have a Creative Soundcard or not, while also giving you modern resolution options.
