I guess WOW and Skyrim are too mainstream to mention by all the hipsters on this board ;)
Personally, I just figured everyone who would be interested in WoW has already played it. As for Skrim, it's a really nice "sightseeing" game, but without mods, there is no sense of mastery to it, so I wouldn't really think of it as something to "sink your teeth into".
Also, Chess is a game of skill much like all gameplay only video games. So it is pretty mindless if you think about it.-mtjormitch
