1 - Everything thing that happened after the first movie I don't want to know about.
2 + Yes, but you're missing out on the part that could be multiplayer where the victims enter the basement and choose their death. Also maybe a mechanic that effects the technician negatively if "the virgin" doesn't die last.
3 - I'd rather have a game about (the first) Jeepers Creepers.
4 - I'd prefer You're Next. It could have a Clue mechanic where you tried to find out who hired the killers.
5 x Never seen any of those.... Now my You're Next idea seem unoriginal....
6 x I don't care for this movie franchise.... But I can't think of anything better.... Maybe Puppet Master.... Create your own puppet & go kill Nazis.... Still too weird for me.
7 x I feel bad that I never watched this film beyond a Simpson's Parody. I'd probably try it.
8 + Any game about a Nightmare World you have to go to when you sleep would be amazing. Why Bethesda hasn't figure this out with Elder Scrolls is beyond me.
