Fun Games

Fun Games have three components (that I can see :D):

1. Basic set of controls or rules that are easy to learn and are satisfying (FPS = shooting guns)

2. The board/playground/level/gamespace must allow for strategic play(i.e. different movement patterns, or things on the board that makes the players want to move there, or different options on different parts of the gamespace)

3. The player must ALWAYS have different tactics at there disposal at any given time (in a card game that's playing different cards, in a board game like risk you can attack/defend/move, or in a game like Halo grenade, gun, other gun, melee) except for the losing state.  (Chess being the example or more specifically checkmate)
