Adding, But Not Math!

Part 3 of 9.  Jeez, this is going to take awhile...

The topic is not so much told through the game itself (but in a way, it kinda is), but more based upon starting with the player's previous knowledge before playing the game.  Examples of this would be "Third World Farmer" where prior knowledge is used to strategically advance in the game.  Other games include "Left 4 Dead" and "Brutal Legend".  One game is about zombies, one game is about music.

Yeah, yeah, yeah, I'm not making any sense...
Rock it out \m/
