There is the ImagiNation Revival at http://innrevival.googlepages.com/

I think there are Duke/Blood players as well. Don't know if they are organized or not.

Mechwarrior 2 community is alive and well and uses Dosbox IPXNet for their games (up to 8 players)

http://cid-0009df616233b826.groups.live.com - English - Death Rally Online Group (owned by me and gvsunde)

http://www.rampagingdragonsclan.freeforums.org/ - English - Doom I & II, Final Doom, Heretic, Hexen, Strife and any Doom-engine-based game (it's a Skulltag Clan, but we are able to play Vanilla Doom and vanilla Doom-based games too thanks to me 🤣; my clan nickname is <RDC>Raffaello)

Any Descent/Descent II as well?

Shadow Warrior?

Rise Of The Triad?

I would really like to play Strife online. Do you play it with dosbox?

You can also play Blood and Shadow Warrior on my site there is a program called YANG (Yet Another Netplay Guider) that you can use to play Blood over Dosbox. It will list your game room on the server list so it's easier to find players.

Added a screen shot attachment

Blood seems to be popular.

Descent is another possibility.

Rise of the Triad community site here:

😁

Blood, Carmageddon, Death Rally, Doom, Doom 2, Duke Nukem 3D, Heretic, Hexen, Powerslave, Quake, Redneck Rampage, Shadow Warrior, Z...
And virtually all great DOS games with network support! 😀

Many games packs based on DOSBox are already available & really easy to use (Install & Setup the games in less than 10 seconds!)
It's a new online community, and we are looking for many players! 😁

"Exclusively"?

Don't use that word.
