Here’s some things I thought I might turn into a game.
The world has been taken over by virtual reality technology, and you’re one of the people still in reality (ONE of. There are still SOME humans not in virtualy reality). After finding some other humans, you have a choice to make. You can destory the main processor and set everyone free forcefullly (which will be difficult) or you can go into virtual reality and convince everyone there to give the real world a try and have them leave willigly, or you can just accept VR and live out the rest of your days there. Whatever you do, know that you hold the ultimate power to change the future for humanity.
(This one is less thought out. It’s just an idea I’m throwing out there) You magically get stuck in your own (or maybe someone elses’) Imagination. Now you have to escape.
(This is just another idea I’m throwing out there, it’s not very thought out) You’re a therapist who has the power to see people memories, but you’ve lost yours.
