I see a few of these guys who did a "reborn at the start of X", where X is like, reiki returns/ghosts world comes/worm holes open/etc., and half the time, they make their MC start with a megacorp. And the first thing they do is cash out their stock. Which is weird. Couldn't they borrow on the assets from banks instead? It's faster, won't tank the stock, and gets them more cash...
