Some usual imperfections - errors in dialogue, many not very believable moments, but I still liked it a lot. It has good characters, great story, it's romantic, even the ending is not too dark, the difficulty is not too high - I only needed to consult a walkthrough near the end. I appreciate it's the kind of adventure game without any time pressure, action or player deaths. I was pleasantly surprised that it's placed in Aventuria, I love it since Star Trail.
Star Trail was a masterpiece. Shadows over Riva is still a good game, but feels rushed, and because most of the gameplay is in a city and the game is too short, you don't put to use good use hunting, camping, exploring, life in the wilderness, what I enjoyed the most in Star Trail. But the game is much easier, also because of this, and I can imagine it's more appealing to non-hardcore RPGers.
I'm writing this review after playing only the original campaign, hopefully MotB will make me change it. But I hoped I would enjoy this game more. I didn't like many of the changes from NWN1. Not only I was forced to have a party (partially by toughness of certain parts), but often I had to take a character with me that I didn't like at all and would kick him out if allowed. The influence system makes it worse. It often made me to take unwanted characters and say things I wouldn't say, just to gain the most inf. OK, reality, but took liberty from the game. Story felt cliched and sometimes confusing, funny at times probably not intended. It reminded me of stories such as KOTOR, only being worse. NWN1 had a simple, but great story which worked for me. I also didn't like strategy elements added to the game, like managing the keep. Particularly, it wasn't explained well enough in the game. Even after patching, I encountered several bugs, some game breaking forcing me to reload. No Time Stop?! Make the game harder in a different way than taking the best spell I was looking forward to from the game! Ok, I was overpowered in NWN1, but enjoyed it. In NWN2 I felt crippled, even when the ending was easy (haha just recalled killing a certain character bragging with power with Finger of Death in a couple of seconds after starting a fight). Not very interesting locations, mostly. NWN1 wins again. It was still a good game, but it lacked the magic of NWN1 where I couldn't stop playing.
