Pretty decent RTS. I like that it's structured so you spend your resources as you earn them, rather than the more traditional stockpiling you see more often in RTS games. Really lends itself to constant fighting. Considering there are basically no new RTS games being made - or at least none that match up to the standards of older titles (see: Command and Conquer, Starcraft, Warcraft, etc) - this is one of the scant few modern games worth picking up for a fan of the genre.
If you're saying that much already then I'm just gonna trust your judgment on this game and hope I enjoy it~ And even if I don't, free games are still nice to own
