I don't even. Seriously.
"Seriously, oh my god, seriously"
Honestly, if they come out and say "It is impossible to meet another player", then I'll be like "fuck you guys, that's bad practice, you straight up lied". But that tweed doesn't say that. And right at this moment, the game has been out for two days, and we do not have enough information to know whether it's possible to see another player or not. The ONLY experiment we have had at least two highly mitigating factors.
That's the short of it. There's nothing else to it. In coming days/weeks, either players will see each other, and this whole thread will be moot; or this will never happen/Hello will announce you can't meet anyone (contrary to what they've said before), in which case yeah, they've been full of shit about this.
I always thought any multiplayer componenet to this game was going to be like Journey. In the sense that I may bump into someone who's at the same point in the game as me, but it's not guaranteed. I don't see this expirment as definitive proof there's no way to meet other players in the game, but either way I was never buying this game for that specifically.
That's 100% how they described it since day one. They never said you WILL see someone else if you're in the same place. They said you MIGHT see someone else if you're in the same place.
