I finished the game a couple of weeks ago, I liked the graphics, some of the puzzles and the many locations. But the dialogues I thought were quite wooden and I was a bit disappointed with the ending...
After I finished it I mused if I had liked the game or not and it's really difficult to say. For me the ending just killed a lot of the fun I had.
Thanks for the Infos on the voice-over, I didn't know. All I remember is that I looked Dracula and Van Helsings voice-actors up, they were both on IMDB.
