Looking for a good Quake 2 SP Level/Mod archive site. Know of any?

I mean, since there's tons of archives dealing with classic Doom, Doom 3, Quake, Quake 4, and ET:QW, I would have thought it would have been just as easy to find such an archive/database for Quake 2 levels.

Yet I can't. Maybe my Google skills are rusty. However, I tried a number of Boolean searches and still came up with nothing. D:

So, yeah, I'm asking if anyone here knows of such an archive for Quake 2 mods and levels (specifically single player stuff). I'm hoping there is and I might have just overlooked it. I know this is a Doom site and all. However, I'd hazard a guess that there's a few people here who like Quake/2/3/4/ET:QW.

idgames2/ has a lot of classics.

I like Quake2. I haven't looked at any mods yets, but know that most of the ports concentrate on Deathmatch multiplayer (often ditching single player mode completely), so I wouldn't be surprised if most mods were also for DM.

Yeah., there hasn't been much SP mods released since like 2000 afaik.

Castles of Stroggo is a good series though.
