yes
Idk about that. You can get a decent experience from watching a stream, but the gameplay itself is amazing. I'd definitely recommend actually playing it. Definitely worth the money.
I haven't purchased a game for full price in what must be over a year now, even longer if we're talking consoles. I was really iffy about this as I tend to avoid full price games, but after seeing perfect score after perfect score from every reviewer, and the gameplay, I caved in. And I can say with full confidence it was 60$ well spent. The experience is amazing, I definitely see myself replaying the story, and the multiplayer is pretty fun, a nice unique idea behind it. And if they consistently update it I'll definitely continue playing it.
It's just one of those games where regardless of the amount of time you spend on it, the experience of playing through it is just so good that it's worth the money. And the single-player is a rather good length for games these days. (15-20 hours if you explore, and it's pretty hard to resist the temptation of doing so)
