I love this game. I have played it through, and the expansion several times. I love the combined arms nature of the game, i like its pacing and the very tactical missions. But i have played the game so many times the missions have become boring. I played the expansion and the sequel, GC 2 does not impress me.

So I am looking for a game that has a lot of the same stuff, just new. So anyone have a recommendation for a game like Ground Control?

*FOOT NOTE* I have played and beaten Mechcommander and Mechcommander 2, i love them for the same reason i love GC but i have played them so much they have gotten boring.

You might try the "Earth 2150" series, Total Annihilation: Commander Pack and it's spiritual successor (if you can find a copy, it's not on GOG yet sadly) Supreme Commander.

Finally, if you ever played C&C Tiberium Sun, EA released this game' code and the mod community went to work on it fixing bugs and creating even more mods from it. If that interests you have a look here, it's free. ;)

A fan made a new expansion called " Ground Control After Math " its a mod with 15 new missions , you can find it at Gcvets.wordpress.com and gcvets.net for more information.
