I got you, but that isn't allowed, and for good reason. Then it's also very expensive, considering developers would be re-inventing the wheel for hardly any monetary benefit.
It's not allowed? Link to this? Or is that just speculation? If they're allowed to do crossplay, I seriously doubt MS or Sony will go "Ok you can do crossplay, but not here, not this part of the game, only this part". At the end of the day both PS4 and XB1 players would be playing with each other regardless which is all that really is on a technical level, there's no reason it'd be "not allowed"
I want to say some games already have in game friends list but I can't think of any other than some PC games
That's extra work for the developer and it's a nuisance for the end user. I hate having to use another username for SFV and the authentication with Capcom's rubbish servers adds to the initial load times.
it wouldn't be another username (well it could be I guess), just have it automatically assign you an ID that's forever tied to your gamertag or PS ID. Also wouldn't need to use it, you wouldn't need to connect to their servers unless you're in the cross play menu. So any servers or load times would only be an issue if you're specifically wanting to play with someone from another platform, otherwise it wouldn't be. Is a few seconds of "optional" loading screen really that much of an issue that you wouldn't want to party up with your friends on a different platform? Lol
It'd be a do it once, done forever type of thing though. It's not like they're gonna need to redo it all for every single game they make, they'd just copy and paste the code over. And developers do stuff all the time without monetary gain (this in response to both)
Come on dude. You are living in a dreamworld. I'd be surprised if they could even display a damn avatar from a competing system.
Avatars are completely different to what I'm saying and you'd need to connect from XBL>PSN for that or vice verser, but ok. Unless the avatar is in game anyways, like CoD emblem editor.
