Just grabbed “power play” on steam which is a new indie RTS game (pretty sure it’s a solo dev). Very similar controls to aoe, theming is modern. Art style is definitely supposed to look old, looks older than aoe lol. Has air+ground+navel combat. Runs great in my 8 year old Mac. No multiplayer matchmaking yet (I think you can play with friends tho) but it’s coming in the future. Very clear counter unit system I like a lot. Each unit has a color coated damage type and armor type and matching damage is strong again matching armor.
Green light weapons are strong against green bio armor for example, or red rockets are strong against red heavy armor. Very intuitive. Currently only 1 faction but there’s supposed to be more coming. Currently on sale on steam for 15 bucks. No replacement for aoe but it’s a fun change of pace.
