Just finished the game, Steam tells me it took me slightly over 40 hours.
Warning: Rambling ahead:
I'm not a huge fan of conventional high fantasy, but I mostly enjoyed playing through it. I however do not expect to play through it more than two or three times over the next years. I'm not a fan of the used ruleset, with real time with pause combat, stuff like heavy armor giving you weird recovery debuffs but not affecting stealth, endurance vs health etc.
While it's a large world, I often felt disconnected from it. Feeling that while it flaunted choice & consequence in front of me, it mostly mattered little. You could easily see which direction the game is pushing you in and how they'd handle alternatives without actually have to branch out from their initial intent.
The quests can be resolved in multiple ways, but more often than not, logical, rational choices appear to be missing. Example: In one quest someone asks you to basically murder an infant. His son then asks you to poison his father instead. These are the only two choices given, outside of just slaughtering everyone in the room. The obviously omitted logical choice would be to inform the other tribe elders, let them sort it out?
Quest descriptions is often either too elaborate (babysitting) or too cryptic. Also don't dare make a logical jump to the answer of a quest, because you'll need to go talk to person X and person Y before you can talk to person Z who has the answer and is constantly named, but you REALLY shouldn't talk to Z because that'd be too logical.
Reputation is nice to have included both on city and faction level, but many times the reputation hits appear to be badly thought out and some actions result in unexpectedly large reputation hits for all the wrong reasons while others go entirely unpunished.
Having your own keep is not very fulfilling either, as it matters very little. You get to restore a bunch of stuff, but other than providing income & something for your unused party members to do, it didn't do much to me.
While the underlying story of the Endless Paths is not a bad one, it's largely a bore to fight your way through it. You're supposed to progress through it bit by bit, as you level up, but it's unclear at which level you're suppose to do it. Meaning you'll end up getting fucked in the ass multiple times without knowing if it's simply a leveling issue or the fact that you're totally missing something. It's not very fulfilling to fight through (though the end boss is more than a challenge if you decide to face it), though I guess it's just an elaborate dungeoncrawl with little more to it.
Plenty of annoying bugs obviously, as you've no doubt heard. Hirelings not getting paid properly half the time, item bonuses not getting applied unless you unequip them & re-equip them constantly between map changes or reloads,... Pathing issues in combat requiring you to babysit all party members at all times.
On the Troika scale, I'd put it far below Arcanum, but a rung above Temple Of Elemental Evil.
