Zero-K

100% not P2W, a wonderful single player campaign, and quite a variety of units. The campaign at the very least, is definitely worth a play.

Have not tried multiplayer, but I will come back to this game for the next few days as I have time. A wonderful RTS for people who like C&C, Total Annihilation, or Supreme Commander.

this is straight up my favorite rts, me and my buddies all got into it and threw 100 hours at it and loved it
