I do not expect you to read all of it

Someone in my office is doing research on video games. (No, I'm never telling you what I do for a living.)
She put out an APB (as opposed to an ISO - I freakin love ISO's) to see if anyone could help her determine If anyone has favorites that have awesome art and a deep fan base I'd be grateful for the name of the game-then I can pursue manufacturer.
As Youngest is a Gamer, I passed the email to him.
His response:

ahem *clears throat*

League of legends 

has some the most amazing art/fan base of any game in the world. Each character has like 5 beautifully done digital portraits for the characters. Though most of the art is made by fans.

Killzone 1/2/3

No, we never did limit his video game time. He seems to have turned out okay.

Presently studying graphic design.  Seems like a good choice.
