Gaming

I know this is a very specific question, but does anyone know anything like this?

What I mean by "like TAB" is that it's an RTS and/or citybuilder where you're constantly under attack from all sides, and taking + holding more of the map is the primary thing that enables you to progress in the game.

Age of Darkness is really fun and I know another update is in the works but I've already played it to death much like TAB. Alien marauder just felt like off-brand TAB and I got bored of it after beating each map once.
