This is how I mainly play the game. It’s cross play with PC but no add on support so keep that in mind. Also once you buy the game on Stadia you do not have to pay anything. Stadia is free for 1080p/stereo, if you decide you like the service and want the monthly free games and the ability to game at 4K/5.1 audio then you can pay a monthly fee.
Also if you are interested in trying it here is a referral code for 2 months of pro.
