Gaming on a Mac is like gaming on a PC just worse. There's less games, every game on Steam that supports Mac supports Windows. Performance is usually worse too. For gaming it's just a worse PC. And it's usually more expensive. And there hasn't been an exclusive worth playing since like 1997. With consoles there is at least stuff you can only play there and an extra ease of use layer plus they are cheaper. Mac is just all downside for gaming.
