I agree with the original poster. There are numerous things I did not like about BD and I feel that it was not a very good RPG (my opinion).
1: People do not get mad if you steal things from their houses.
2: The reputation system did not seem to exist, maybe it was just me.
3: For me, all the side quest were very linear. They seemed to be all "I need something/I lost something" and the response your character would have, "Ill try and get it". In Divine Divinity I loved the side quests. They gave more background and were more complex. Hell, the side quest to expose Dr Elerath and cure the illness was better than the main quest in BD to cure the illness in the imp village (my opinion).
4: I know everyone has already mentioned it but I need to add it. Clicking on neutral animals.
5: Like the above poster said, once you complete an act you are done. You can not go back.
6: I did not like BDs atmosphere. I guess when I imagine hell I dont imagine a level one character being able to survive there. In DD everyone had something interesting to say, not so in BD. 90% of the imps in act 2 say the same thing and do not even have portraits. I must admit though that act 3 was alot better at making a town come alive.
7: Lack of responses for main character. It seems the only response my main character could say was "I agree" or "I dont have time" when accepting a quest.
8: ALOT of bugs, but DD had a ton of bugs also so I wont hold that against it.
In conclusion I felt that I had to drag my feet throughout the game. The only thing that kept my going was "I wonder what happens to the death knight". It was like having to eat chips of crap to get to a pizza. I do thank Larian for listening to their costumers and I also think Larian will fill the shoes of making great CRPGS. I believe larian will make alot of great games in the future.
