Mario's Castle

Paul Eres of RPGCreations (creator of Immortal Defense) is planning a five-year come back with Saturated Dreamers, an open-world, story-based, action-adventure, exploratory game due late 2012 for PC.
Saturated Dreamers follows the scientist Mercedes who is sent to the ice planet Lake -- a sentient, alien lake-world -- to search for the remains from a previous expedition. Players pilot a multi-purpose ship to explore and purify the Lake, friend its creatures, and find and equip new abilities.
