I used to play a Korean developed strategy MMO that seems very similar to this, but I don't remember what it was called. It has different stats that you could level up that would affect how your units performed. One of them was called "clout" and limited what units you could purchase and how many units you could bring into battle. There was also a world map with a few different factions and tiles that you could capture to gain resources. How similar is what I described compared to this game?
--Edit--
Found the game I used to play, Shattered Galaxy, it's 11 years old! I had to quit because I didn't have a credit card when the game came out.
