I got Q!Zone running on WinQuake. Everything worked fine.

There are a few interesting levels (e.g. an airplane and some houses), but as a whole level design is poor. I suppose we can make better levels than these guys :P

Most semi-official mission packs were horrible, but there were a few good ones. Duke It Out in DC (for DN3D) is pretty good and on par with the original game. Cryptic Passage (for Blood) is amazing - in fact most fans consider it to be better than the official expansion for the game (and I agree with them).

Nowadays, it's not just add-ons that have disappeared. Modding or making custom levels is not as popular as it used to be. In fact, most modern games don't allow you to modify stuff, so the players' creative potential is lost.
