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.
Creeper World is sort of like this. Basically the enemy is a self replicating liquid that destroys everything it touches and you have to fight it off and secure each map. It was originally a flash game so go with those expectations but it's pretty fun regardless. I recommend CW3 as the best one.
That game was probable the first proper RTS I ever played, or is at least the 1st I remember.
I was probably 10 y/o old or younger when I played the OG flash game.
Never played CW3 but I have played CW4 and it definitely scratched the same itch as the OG, what about 3 makes it the best?
