The only game I had in middle school for PC that wasn't education focused was Star Wars Empire at War. I ended up learning how to modify the files to change things like unit stats, unit cap, faction, etc. In particular I remember deciding that every space ship should be it's own unit instead of the squad being a unit and ramping the unit cap up to a crazy high number then having giant space battles. Also I really liked the pirate units so I think I gave those to both the Empire and the Rebels.
