I started Far Cry Primal over the weekend, since it was on sale, and I'm enjoying it a lot more than I thought I would. The gameplay is Far Cry-standard stuff, but the setting makes it better in a number of ways. The lack of vehicles slows you down, obviously, which improves the exploration aspect of the game and makes it harder to flee predators - I had to jump off a cliff to get away from a mountain lion. Your meta-mission to gather your scattered people and establish a new home gives you a plausible reason to get out there and find trouble (the main character's involvement in the previous games always felt tenuous to me), and seeing the village grow is kind of gratifying (you don't do it all yourself, thank god - with the exception of a handful of special buildings, the people you rescue and/or recruit construct the additions while you're away on your adventures). And there's some novelty in the Stone Age setting, which is important to me. It isn't as creative and interesting as Subnautica, and there is a little bit of 'magic', but at least it's not another [gosh-darned] pseudo-Medieval Europe Tolkien/Howard ripoff.
Initially, I started playing on normal settings, but after 3 or 4 hours I went back and started over on Survival Mode. So far, Survival Mode seems to make many of the game's systems more important, and seems to be where the game is meant to be played. It dramatically cuts the number of weapons you can carry (1 club, 1 spear and 4 arrows initially); makes night darker, longer, and more threatening; and makes more of the Skill Tree useful. Crafting is still much too easy and fast. I'm considering a 'roleplaying' house-rule, where I'll only craft when I'm at the village or in one of the camps.
