I was planning on running this game on my m3 2016 rMB. I have it in my time machine backup; I'm just waiting for my USB-C to 3 adapter to get here. I'll let you know how it performs when I test it 🙂
EDIT: Scratch that, I just remembered I downloaded it from the App Store. Installing now; you won't have to wait as long lol.
EDIT2: Just played part of a free for all match. Ran great! My computer got a little warm though, so keep that in mind if you intend to play longer sessions.
