This is just an idea, but I think it enhances the gameplay quite a lot (for both 2150 as 2160). I think it is a must for every earth fan. What it basicly does is adding game modes to the skirmish mode, such as team battles.
It would be great if GOG were to host it as well!

Is the gog version of e2160 actually compatible with mods?
e2160 had quite a lot of community balancing going on and the version included in the most recent patch (which I guess is included in the gog release) is older than the most recent one used by the community.

In addition to Superstorm, there were quite a few funny mods, for example chess.
