Well to avoid spoilers I will talk in the most generic way possible. In my humble opinion the game should had been split in 4 acts, act 3 feels there is tons of stories going on at the same time and some of them are not concluded properly. Stuff that should had more time in the spotlight to do proper justice and be presented in this final act. While could use the extra act to unload the load and let people have time to enjoy Baldurs Gate city.
Its an excellent game but you notice the quality drop in ACT 3 and the ending.
