Actually, this deal doesn't seem like a "no brainer" to me. I've been dragging my feet about this deal after reading it.
Maybe because I'm a PS4 guy (but I do have an Xbox One X).
I'm looking at the games on Game Pass, and none of them really interest me. I don't need an active LIVE sub because I don't play multiplayer games that require it (I'm not even subbed to PS+). I don't know what the point of Game Pass on PC is (if you have an Xbox), since most games are Play Anywhere.
I don't mean to crap on the deal, it's just me sharing my thoughts on the value assessment (being a typical cheapass), and figured this deserved to be put under the lens. If I missed some aspect of this deal, let me know.
It's a no brainer if you actively subscribe to Gold or want to, not just everyone no matter what. If you have Gold, you are basically extending it one month for $1 plus getting GP for PC and console for the length of time you have Gold. That's a no brainer value for a buck (if you have use for Gold).
Also, you can't find anything worth playing in that list of games? Wow. It's not mindblowingly amazing, but there's a lot of great stuff in there.
It seems like there were only 10-20 play anywhere titles included beforehand and now they tout that the PC gamepass includes over 100 games. I'm sure there are plenty that are also on console that aren't play anywhere that are now included on both.
That said, as you said, it's not for everyone, but nothing ever is.
