Text feedback as requested:"real-world physics"
sounds like an exaggeration (a lot of it isn't realistic), "simulated" perhaps?
(same deal with "realistic explosions")
Tactical possibilities aren't limited by one's technical ability
Probably because of my programming hobby, but "technical" here sounds more like "skill with computer code and other such things" than "APM"
(because I'm that kind of person, I tried and failed to come up with phrasing that doesn't imply having things like muscle spasms or blindness won't impact the game at all)
Some minor stuff:
A powerful interface allows players to easily implement their economic, strategic, and tactical decisions
"execute" would probably be more correct than "implement""Spider walkers"
should be just "Spiders" perhaps
(also maybe remove Tanks, since to people outside the context of the game it just sounds like a subset of Vehicles)
