Great idea..I spent many hours playing road rash and roadrash2. I could see that working providing that they would allow the development on it. I think it was electronic arts if I remember correctly.
Actually all of your ideas were pretty on point. I develop but have not done much on games though. After experiencing the paranormal teaser game, I think horror games could do really well. I was thinking of putting my efforts towards building a game that would allow the user to use simplified tools and generate their own game, such as a long haunted house. Allow the user to structure it , decorate it , choose the scare points. Then allow it to be packaged like a custom made level and distribute it. I spoke with one of the companies who makes the monster layouts and they are interested if I can structure it be an add on or plugin with a small but reasonable cost for themselves, this would also help to ensure some quality graphical designs and possibly allow for crazier items that they couldn't normally do live. The vr world seems to need this kind of a boost or push that in turn would draw more people into having some kind of ability to have a role even if it's a small one, seems like everyone wants to be behind the scenes as a part of something bigger and not just a player who plays it through once and never looks at it again.
