Preloading (in sense of videogames) is when you are able to download a game before it's actually been released and available for everyone to play. So when the game is out, you can play it instantly if you preloaded the game.

This is very useful to people who have slow internet speed, so they won't have to wait for a long time before they can start it.

(noun) A successful type of theft which results in an acceptable, impressive and rewarding payday for the protagonist.
