Last night's dream: Borderlands but with Doom finishing moves.
I'll call this The Doom Initiative: by law, have game companies be forced to release the source code of their games 5 years after release. No exceptions. And for any game that is reliant on a web server to run, release that source code after 10-15 years. If you don't comply, your company gets the equivalent of a death sentence: gets forcefully dissolved.
And in that spirit, video game related ideas:
a toggle for content warnings for gore, but the game becomes gorier with it enabled.
