Mostly you have to look it up on a per game basis. Probably just Google the game name and “supports cross play between” whatever platforms you want and someone will know

Depends entirely on the game. Some games yes some games no.

Valve doesn’t care one whit about good moderation. I got kicked from a CS game recently because I wouldn’t say the n word. The team agreed that only racists are allowed on the team and since I wouldn’t say the n word they kicked me. Of course I reported all of them but I have no doubt that report falls into a black hole and the 4 people proud of their racism just get to keep playing as if nothing happened.

Riot does a ton of things very very wrong but one thing they do a decent job of is actually punishing people for bad behavior like that and then notifying the reporters that hey, you helped us get those guys. Valve needs to take that kind of approach or their games and services will just continue to be overrun by this shit

It’s just standard cape shit. Liberal optimism is a hero saves the world so I don’t have to care!
