There are no twitter stocks, you can’t buy or sell them, and therefore can’t short them, since you need to borrow them to do just that. This could work if Elon had some percent of the company, so other people’s money would enter the equation, but right now it is not possible.

Most of those are already shit (Fallout, Diablo, Overwatch, call of duty) or shelved 25+ years ago (Commander Keen, Hexen, Phantasmagoria…). Microsoft’s own games are rather good compared to Activision Blizzar or even Bethesda.
