Compared to its predecessors, this game falls incredibly short in almost every area. It has been a good few years since I've played the game but I don't really remember much about the story at all besides the Didact and the composer/Prometheans. The change in art style felt like conformity instead of a thoughtful change in direction. The Prometheans were definitely a pretty cool concept (despite what a lot of people believe) and acted as another attempt at adding another enemy faction into the mix. Overall just a very "OK" game and while I have played through it a fair number of times I don't think I want to try and play it again for a while.
