Its here.

The ultimate RTS.

--DUH102 INTERVENTION--
SpringRTS, more a game engine than a game persay.
Programmed by a Total Annihilation playing clan, the Swedish Yankspankers, the engine relies upon the mod (game) makers to provide content, and there are plenty of TA-based mods to go around. However, to legally play these mods you must own Total Annihilation.

There are several very well made mods that do not require a copy of TA, even including one mod that attempted to go commercial.

(apparently at time of this writing, AI is broken, but once it is fixed this will apply)
AI is controlled by plugins, both enemies and helper AIs. Several advanced learning AIs have been created that learn your playing style and how to most effectively make use of both units and terrain. Notables include AAI, RAI, and KAIK.

Maps are created from a composite of images and a metafile, namely a heightmap, texturemap, grassmap, metalmap, and featuremap. They can be very beautiful, if the maker takes his time, with such masterpieces as General Cai's Revenge (something I pulled out of the forum, I expect there are much greater examples of mastery).

The physics are quite decent for an RTS; Units do not have a random chance of missing but aiming discrepancies that might throw an artillery round into your own territory if you're not careful.
When units explode, their parts fly everywhere, so that a nuclear strike looks positively beautiful.
Terrain deformation affects the passability of terrain, so that nuking a mountain road might create a crater that is impassible by less-agile vehicles while kbots may still pass, with difficulty.

All in all, well worth your time if you would like to take a look.

NOTA
--DUH102 INTERVENTION--

Been playing it for awhile now. Its a bit glitchy with the AIs, usually not initialising.

All of the mods suck, the AI doesn't exist, the community is filled with retards and it inexplicably doesn't work on my new computer.

It does, it just got broke in the latest update, and was broken before that. I had it working on the WW2 Mod but it broke again.

So it's never worked.

The AI worked fine in v0.75 (I think it was 0.75), that was the last version I played. Very good engine/game, I played a lot of NOTA.

How about actually linking the game and posting some info?

i think i'll stick with C&C generals, C&C red alert, Wc3, SC 1 and 2, and the greatest freeware rts ever, glest.

I'll do it, I have the time and technology. I can make it better, faster, stronger!

I tried it but no matter the mod the atmosphere is so blah it kind of takes away from ti.

Yeah, Glest is pretty much the best free rts I can find on the internet.
