i'm not sure about a whole game, but i do have an inovation in gameplay that might be good (you tell me, i wanna know what people think)
Ok in a game like Oblivion. you're in a battle, all of a sudden you get hit. the sword breaks through the armor and cuts pretty deep and you start bleed. you get a gauge on the screen that shows the amount of blood you have left until you black out. You can heal youself using magic or something, but it takes a while so you have to kill the guy first. If you black out, you have X amount of in-game time (that goes by in a second) where you hope a friendly NPC finds you and revives you. if not you die in the wilderness or get eaten by animals, or the hostile NPC's rape you (not really you just die if you're not found.)
Also in an Oblivion game like setting. have body parts that break and can get cut off. so you'll occionally see an NPC missing a leg or arm. or in the middle or battle you can break the bones of your opponent and he'll react accordingly. so if you break or cut off his legs he'll just sit there for you to finish him or let him blackout and be eaten or something
What do you think. Good or Bad
