I personally wish someone would take the IP for jeepers creepers. Hey you never specified what kind of IP. That said, it's been 12 YEARS since the franchise had any activity.
Hell here's a pitch: open world game, you play as everyone's favorite.... demon, I guess you could call him that. You can run at ludicrous speeds(think like in the prototype series, which now that I think about it could also use another game right about now) and fly like in the movie, search for people, smell them and scared them, maybe even have a chance of them ruining their pants if you can scare them enough, and then take whatever you...... like. From there maybe have it so you get the parts and spend parts to upgrade your abilities and make yourself even harder to kill, though I would rather have a skill tree for take-downs, durability, and weapons you can carry while the more lungs and heart you have the faster you move, the more eyes the farther you can see and detect someone,ect, and if someone shoots you, then you have a chance of loosing the corresponding organ (ex:shot in eye, loose that eye and now you have trouble seeing, shot in chest loose a heart, though it's more likely that it would hit a lung logically given the size and the fact there's one on either side of the heart.... getting of topic though) and if you get shot in a limb, you loose it and have to get a new one. I now have an image of an hillbilly with a shotgun blowing a leg off right before it flies into the air and grabs his friend for a replacement limb.
The whole "23"days thing would probably be a difficult thing to work in. I can think of two possible methods: (A) like Arkham city time progresses as you work your way through the story or (B) do something similar to dead rising and have time progress, just at an accelerated rate, say maybe one day equals a 3, maybe 4 hours? So a single playthrough would round out to 69 or 92 hours respectively, assuming the game doesn't have a mechcanic like, say taking a person to it's house of pain and make them into weapons like those knives or the shuriken with danny's belly button would take several hours. I would rather it be instant than take time.
