I was scrolling through the posts tagged with "Game" and noticed that it involved quite a few code golf competitions. Just for the sake of clarity and ease while searching, I believe that the definitions of some tags should be clarified to be as follows:
- Challenge: A play thing with an objective.
- Competition: A challenge taken by multiple players where the players can not interfere with each other, but otherwise are trying to be better than the other players.
- Game: A challenge, except that the players can interfere with each other.
I got the definitions from this Vsauce video starting at around 2:45
Under these new definitions, a typical code golf should be tagged with "competition", things like "king-of-the-hill" are classified as a "game".
