Here are my inedited notes that I made while playing, in case that helps you decide, no guarantees though (it's been a while, and some things I wrote down I don't quite understand myself anymore):
+ great soundtrack by Inon Zur
+ yes, it treads well-known paths, but in a very competent way
+ humour, characters and voice-actors (bit stereotypical but well done)
+ great character creation screens, you have quite a few interesting options but you get short and helpful explanations for everything, and you can freely switch between the tabs, e.g. change your class retroactively, AFTER you've already fine-tuned your appearance, without losing any changes.
+ camera controls are a bit unusual at first because completely opposite to games like NWN, but they work fine once you get the hang of it
+ 3D areas are nice to look at, almost like in the games with isometric perspective, and the view is generally much better than in NWN2
+ puzzles are easy but nice and satisfying
+ you can directly travel to most areas you've been to, including caves and crypts, without having to pass through the outdoor area again ...
- ... but once you're there, you need to find a world map transition to travel back, and that can require passing through several or larger areas
+ one inventory for all party members ...
- ... but how much all of you can carry is determined only by the strength of your main character, making the game less convenient for casters in this regard
+ /- fallen party members can easily be revived, if another character can get to them without interference, or even after the combat; if the combat ends while they're incapacitated, they don't get XP for it though
+/- contrary to my usual preference for Normal, I chose Hard mode, and then I played the game more tactically in real time with frequent pausing and party AI off; it was occasionally challenging but not that difficult, and after you've really understood how the game works, most fights were no problem. I was confused at first by unfavorable reviews comparing the game to Diablo, but I guess if you play with party AI on, and possibly in Normal or Easy, too, you can just waltz through most encounters.
+/- party members don't do a lot of damage, opponents often have very high hps; among the best spells is Hunter's Target, who gives combat advantage and increases damage against a target by 50%, thereby speeding things up a little
+/- has an option to move loot into a junk category and then sell it with one press of a button, but since you'd need to right click on each item and select "Junk", that actually takes more steps than just selling the junk directly
- long loading times
- in the location where the party stash is (so the most likely place for inventory management), you don't have access to your companions' inventory
- as far as I could tell, you can't customize the party AI behaviour, just turn it off (party members won't do anything on their own) or on (party members will follow active character and use spells and skills)
- party members are auto-attacking once you give them a target, which is generally fine, but can get in your way; for example if you have one character cast a Sleep spell on a target and you don't give them something else to do immediately after, they will keep concentrating on that target and engage it with their default attack, thereby waking it up again; sometimes it also happened that when they killed someone, they chose a new target of their own accord, even if AI was turned off - no idea why (it wasn't Cleave)
- account required, what happens when accounts get shut down?
- manual saving possible, but only in a single slot, character and savegames are probably stored online; autosave, can be turned off
- if you save and quit, then load your savegame the next time, the monsters who had been under your control (animate dead/create thrall) are gone
- 4 companions but player can only have 3 in the party at the same time; at least of the initial companions (Jarhild) the one left behind doesn't gain experience and will soon be several levels lower than the rest; the companions that aren't in the party can still comment on events; so there's no good reason to change your party composition mid-game, you'll most likely stick with the companions you meet in the beginning
- there's a mission where an NPC accompanies the party and fights alongside it; he's quite squishy so that his health gets reduced quickly by attackers, but then never goes below 1 hp, so the party can abuse him as meat shield; would have been better to make him part of the party, or make him much tougher but able to pass out (wouldn't have been such a big deal anyway, seeing that you can always revive fallen members as long as at least one character is still standing)
- when the duration of a conjure animal or animate dead spell is over and the creature vanishes, it does so with a horrifying cry of agony and/or an exploding sound that always makes you jump and think someone has attacked your party members or they ran into a trap aor something - much ado about nothing, these sounds are quite exaggerated and counterintuitive
