I'll post my over all thoughts/brief review of the game here so I don't have to mess with spoiler tags in the OT or Review thread.
Overall I had a good time with it. I'm shelving it for now (maybe for good) at level 87 (other 3 at 85) and a bit over 67 hours played. In terms of post game/optional stuff I got all the kings arms, did all the optional dungeons, got the key to open the 8 sealed doors and did the first one of those (Keycatrich Trench) and did the Pitioss dungeon. Side quest wise the only ones I've found that I haven't completed are a bunch of hunts, a fishing quest (level 28 one), frog lady quest line, Dave/dog tags (don't think that's done) and Randolph's quests (have the level 85 one in my list have done the lower ones).
Pros:
-Beautiful world that was fun to explore despite being mostly barren
-Liked the bros
-Enjoyed the combat as someone that just stayed overleveled and didn't learn the ins and outs really. I don't care for combat in RPGs in general, I'm here for the questing and exploring--and usually the characters and story
-I loved that it was easy to overlevel without a ton of grinding (again, I'm not there for the combat and end up playing a lot of RPGs on easy)
-Game just has some odd charm too it. Maybe it's the odd blend of WRPG and JRPG sensibilities
-Liked the Prompto photo gimmick. As someone who rarely takes screen shots, it was neat looking through them after missions
-Dungeons were pretty decent for a recent RPG
Cons:
-Story was a dumpster fire. Poorly told, and even if it was more fleshed out I just didn't find the story or lore compelling at all
-Lame characters outside of the bros
-Wish they game had more dialogue options to build up the relationship between the bros (and others) more. I'd have liked this a lot more with something like a Bioware dialogue and relationship system.
-Glitches. Only one I got was that my 40 sidequest completed trophy glitched some how--have the 80 quest one and the smaller ones, but not that one. Thankfully I missed the others that people have posted about.
-Not being able to advance time of day--should give you the option when selecting the quest in your log not just when accepting a hunt
-Only being able to carry one hunt at a time
-Terrible load times
-Didn't find the Pitioss dungeon enjoyable as the controls and camera aren't suited for a platformer IMO. Hard to knock the game for something totally optional though.
Overall:
I'd probably give is a solid 8.0. It's a very flawed game with lots more I could nitpick than the above, but I enjoyed my time with it. I'll probably revisit it eventually--especially if they patch that trophy glitch so I can push for the platinum (think all I have is Adamantoise and getting fishing, survival and cooking skills up to 10--survival is at 9 other two at 5 I think) and/or if any of the DLC ends up being decent.
