I've seen many new art games lately here on Armorgames. Some people don't seem to understand it and see no 'game' in it. Now I suggest that there should be a new genre, so it's clear to everyone that the game isn't just for fun, but that it's a game that makes you think about anything.
Some "art" games are also puzzle games while others are put into Misc. They're always, or almost always, RPGs. There are not enough "art" games to fill a full page.
