Playing Mysteries of Westgate now.
At first I liked it. The single city setting is cool, the premise of a mask you can't get rid of is interesting potential for investigation, etc.
However, from there it loses its way. I found very early on that the game is completely littered with skill checks that don't actually check your skills, for instance. Doesn't matter what your persuade/intimidate/charisma/dexterity/whatever is, there are times where you will always pass or always fail simply if the plot demands it, and they only give you the skill "checks" to broadcast the illusion of choice. There is almost no point to getting any non-combat skills because the few situations you do get "real" skill checks, the outcomes aren't significantly different whether you pass or fail.
Same applies to quests. Pretty much all the quests are 100% linear and proceed exactly the same very time regardless of character build. You don't have a choice to side with X or Y characters, no chance to use your special skills, nothing. Whenever you do have a choice, the outcome is identical every time. The only choice I can see is that you can side with the church or a criminal organization - but these quest chains are very short and uninteresting, usually just involving one small location with a fight or two.
Alignment and influence seem to have no significant effect. Alignment for me hasn't been altered once (I'm neutral evil and working for the Lathander church with no alignment shift, durr?) and hasn't affected any choices I've made. Companion influence seems to have no effect anywhere and from reading online, there are only two points in the game where it ever makes a difference (and it's tiny).
The number of side quests is quite limited, but the ones that are there are actually more fun and more extensive than the main quests I've done so far. The city itself is very small and there is pretty much no exploration to speak of. There are almost no non-quest NPCs to talk to, almost every door you find is locked until it magically opens for a quest, and so on. Only three districts, four if you count the Undercity or whatever it's called. So far the best thing in the game has been the semi-hidden "Order of the Ferret" quest with one of Boo's, uh, space-hamster-friends.
Really lacking in polish. Could use a bit more voice-acting, especially in the main story scenes and for major characters, yet there is very, very little except for the intro of the game. Some of the cutscenes you do get border on incomprehensible because the camera/animations/etc. are really glitchy. The environments are almost all universally dark and it can be very hard to see anything, even with night vision turned on. I have a feeling their level designer had some sort of gamma-boosted monitor, as all the official screenshots look way brighter than the actual game.
Best part of it is the combat. It's actually challenging, you don't get too much loot to imbalance everything, and I needed to use strategy more in it than any other NWN game. Unfortunately there is no mage companion, and you can't multi-class followers, which means that if you don't pick a spellcaster for your main character, you are fucked.
Long story short, feels like a mod made by 1-2 people that received almost no outside testing and feedback before release. Probably was, knowing Ossian Studios, however, as a paid product I have to say it's pretty underwhelming. It's not even that bad, just missing that extra 20% that comes from play-testing, non-critical content, etc. Could have been good if it wasn't for the above problems.
