I liked it better than Brotherhood, mostly because the setting was fresh. I am in minority though. Worth checking out, because it is quite possible that the relatively harsh reception of Brotherhood was more because of series fatigue than the quality of the game.
I knew Ryse would happen someday. Bought in on sale for $10 (the complete edition) and it was decent. Not too mad about that one since I knew it was happening.
Never finished Season Two proper so will play that. Darksiders is nice but with remasters now it makes it less tempting to try. AC Revelations would be pretty meh too but it will reignite some of the most fun multiplayer on XBL so I'm down (same applies to Brotherhood and I believe all the AC games up to 4)
Stuff ends up in GwG/PS+ for a lot of reasons and the availability of better versions you can upgrade to or lots of DLC they can sell you are some of those. It's helpful for the publisher to justify inclusion. So whilst it would be nice to have the X1 versions, they are part of the reason the titles are included in the first place.
