Tribe 8 in the Dark Alliance style. For Downloadable service(WiiWare, PSN, Live, PC). With extra content purchasable as it comes. I can almost garuntee no one on this forum knows what the hell Tribe 8 is. If you do I'm not refering to the female band.
Tribe 8 is a postapocolytpic world where the fall of civilization was caused by a flood of spirits crossing from the other side. Think of something like Ghost Busters 1. As time goes by they go instaibly hungry of fleshy desires and proclaim themselves gods. They are then trapped to live in bodies of flesh like prisons. many go mad. The world falls into various ruins. You end up with this awesome mystical, horror, apocolyptic fantasy setting. Seems like you can't mix all of them together, but it works so darn well.
You have the Tribals who were lead to freedom by the Avatars of a God.
The Keepers who seeled them selves away and hold onto the world before Knowledge. Keepers
Squats, people just managing to survive.
Serfs, willing servents of the monsters.
the monsters of course. power beings that are more psycholigly horrific and powerful.
and so on.
monster contrstructs. this allows for plenty of freedom for more classic monster types. Werwolves, gargoyles.
It would be Fantasy, so swords, monsters, dungeons(world before ruins, like Fallout), with occasional guns. With the known backdrop of earth. it's just got that vibe too it.
