Ya, mark me down as another one who talked an extraordinary amount of shit about this game before launch and ended up really enjoying it. Finished it last night at 16 hours with 50% completion, will go for the Platinum Trophy as I did for Far Cry 4.
Combat is mediocre, story isn't even really a thing, but everything else is a huge leap forward for the series. The sound design and positional audio is absolutely incredible. I was just using basic TV speakers and had more than a few situations where the audio cues were a more useful indicator for danger than the minimap, that impressed me greatly.
The game surprised me in a number of ways I didn't expect it to, but my first impressions of the combat were spot-on. The removal of guns removes the variety and combat encounters ended up becoming repetitive and "samey" far more quickly than the previous games, to me. It's my largest complaint by a country mile.
The open world itself is such a huge step forward for the series that it makes up for the weak story, for me, but they really needed to overhaul the melee combat if they were going to go for something like this. No blocking, no parrying, just mashing R2 until someone falls down, with some occasional dancing around in circles to heal. It was weak.
I think Ubisoft Montreal deserves great credit for building one of the most atmospheric and immersive open worlds ever. I'm jaded as fuck and there were still an astonishing number of moments where I just stopped and took everything in. World-building is absolutely TOP FUCKING NOTCH here, it was a real joy to explore and just get lost in. The main story quests may feel like other game's sidequests, but the world itself, again, makes up for that. I don't need big, over-the-top setpieces when the environment feels so alive and begging to be explored. They did good.
So, 8/10 that could have been a real 9.5 or so with a more complex combat system. I can very easily see how the combat might not be as much of a detractor to some as it was for me, it wouldn't surprise me in the least if Primal actually turns out to be a series favorite for many. What it does well, it does extraordinarily well.
