Really cool game and I love being part of the early stages of the game's development as a player.
My biggest recommendation is to please add a 2nd faction as soon as possible and don't just stop at 2! Lets use 8bit Armies vs 9bit armies as an example, 8 bit armies had 6 factions with all the DLCs versus 9bit with still only 2 factions; gameplay gets quite repetitive with so few factions. They don't even need to be super unique, even just a different skin and different unit textures would be fine for the short-term.
Pros: Active developer who is updating and patching the game little by little probably every day.
Not a pro or con: Just a warning, still incredibly early access with a lot of improvement needed in regards to combat, more maps, bigger maps, and etc.

Very promising RTS. Following the develpment for ages and playing since beta times and bought it on first day of EA.
Very active development and really fun to play.
Every new iteration brings something new and I am looking forward to what will come.
