I don't know what other people think. I can only speak for myself. For me DSC wasn't interesting enough. The dreams just weren't really "dreamy". The only one I really liked was Jack-the-Ripper-London.
Dreams have to be crazy and weird. Like Alex's dreams in LF. I found those dreams much better.
In DSC some of the dreams are normal dungeons like in other games. The caves for instance. There's nothing "dreamy" about them.
The concept of travelling through dreams is great I think. It's just that the dreams themselves were not what I expected.
