I'm here to solicit good fanmade RTS. Anything that adds either a good new campaign, or good new faction design into the game, or preferably both. I'm playing Rise of the Reds, and it sold me on the idea, but I also know about the following:
-Legacy of the Confederates (SC1)
-Mental Omega (RA2)
-UED: First Light (SC2)
What else should I look into?
I liked the Contra mod for C&C Generals. It adds a whole bunch of units for every general, making them more distinct from eachother, and also a new general for every faction. Don't think it has a campaign, but it updates all the general challenges to use the new units and buildings. It's a bit on the ridiculous side (nuke general gets a nuke array that basically deletes a section of the map if you let it count down from 15 minutes, stealth general gets tanks that are permanently invisible and have sniper cannons that oneshot nearly everything on ground) but it's a lot of fun and I spent many hours playing PVP and comp stomps with my friends a while back.
Speaking of Rise of the Reds, was it ever finished? I remember trying it and thinking it was cool and the devs promised a bunch of features like generals for each new factions and a campaign but then just went silent and I checked ModDB recently and the last files were still from 2015.
There's also a bunch of work in progress mods for RA3 that look promising.
Corona (lol) mod adds China as a new factions and new units for the existing ones and the new units look very professionally designed and don't stand out from the rest of the game.
There's also RA3 Rejuvination, which adds sub-factions similar to Generals and the new units also look very much in line with the rest of the game with custom voice acting. I only recently learned about it through random recommended vids and checked ModDB. It's playable but the dev said he's putting work on hold due to personal problems.
