There have been more than 2 XCOM games.

In Link's Awakening, there's one dungeon where, with a precisely timed jump and use of the dash boots, you can get across a moat before getting the dungeon's treasure, which gives you the ability to swim. Save here, and you're at one of very few points in the Legend of Zelda series where you can get stuck permanently

some debuff that killed a bunch of people in WoW was going to be used for real world research on infectious diseases

Atari could've owned (literally, they had a deal in place for it) the NES back in 1983. Imagine that parallel dimension for a second.

in Grand Theft Auto V: If you go on the phone in the campaign and type the number 19993673767, your phone will blow up. If you pull up your phone again, it will be a different bigger phone.

Did you know? I actually could tripple jump in a released game not too long after Mario could! In Christmas NiGHTS into Dreams, there was a mode called SONIC into Dreams where you could play Spring Valley as yours truly! I even had a special boss fight against Eggman that played like fighting Puffy in the main game. It even had it's own music called "Rolling Eggman". Isn't that way past cool?
