I remember that the biggest of those Dam, the Green Dam, took me just too much time. I remember I started in the early morning, pausing almost only to eat and I fininshed it in the evening. I could only explore one or two more places, trying to undurstand the maze, and one of my caracters died, had to teleport and start again. And again...

Right Now I'm doing PSIII for the first time and I find it much more easy than PSII in general.
