My idea in bullet points:
* Multi-platform
* Slient protagonist
* About 30 hours in length(20 per playthrough)
* First 10 hours set it up(ie *10 hour Taris*)
* Set at High School(Taris High)
* Sparkling vampires, obsessed with a special ring
* You join a elite group to battle this menace
* Or join an equally elite group to assist the menace
* Distinctive good/evil paths (7 hours each)
* Based on one choice(* he he I go bad*)
* Lot's of tunnels, but no fighting in them
* 3 endings(good/evil/true)
* Bugs
* Lots of DLC (Most of it substandard)
