Title says it all - is this something that will potentially happen in the future? I want to play co-op with my friends but don't want to purchase more Stadia remotes, because I already have Xbox remotes.
@Jbigbee I haven't heard about any progress on supporting third-party controllers for gaming on Chromecast. That might be tricky since the Stadia controller is using the WiFi network to connect directly to the server hosting the gaming instance.
I do think it would be cool to be able to use a phone with the Stadia app as a "host" for connecting other controllers into the Stadia universe but I don't have any idea if or how feasible that might actually be.
Definitely send feedback through the Stadia app to let the team know this is something you'd like to see though!
