I caved, today. I bought Star Citizen.
Well, pledged to it or whatever it is.
Downloaded it. 12 point something gigs. Then it said "Ohhh, hahahah mate, we're not done with you yet. Time to download another 50-odd gigs more." Sighed, and went for a poop while my computer did its thing. (Didn't take long, I have gig speedz. Internet, not the pooping. That'd be nice, though.)
Came back, my PC had crashed on first run. Hooray!
Had to download again. This time it seemed to go okay.
Managed to create my character (basically their holo-me) and started the game. Took about five minutes to actually load my... bedroom.
After about five minutes of puttering around in there in confusion, my PC crashed with a temperature error. My fans were screaming. Absolutely could not reboot without it, and my CPU was showing as 75 degrees C in the bios under zero load. Absolutely never happened before. Unplugged, let it sit for 15 minutes and opened the panels to let air in. My AIO hoses were hot. The pump head of my AIO was hot. My GPU fins almost took a layer of skin off.
Finally tried booting again and Windows wouldn't let me, and had to go into repair mode. Where it basically uninstalled Star Citizen for itself, and then booted right in. Temps are now completely normal again, tried a few different games like ED and Red Dead Redemption 2, no issues there.
