Just run BootCamp for gaming.
I got my Mac when Intel processors were dreams and ideas and when Boot Camp was almost impossible. I might buy a new computer or Mac Mini or I might buy more RAM, memory, and a new graphics card for my ME PC that can’t load internet, although it’s probably because I have crappy internet in my basement…Ah well.
You probably won’t be able to run WAR then. I’m barely running it on my old beater, but it’s probably got better specs than your machines.
