There are three main reasons I enjoy playing a game. They are as follows:
- The story latches onto me like a pitbull convinced I'm smuggling prime rib in my trousers.
- There is some element of social interaction that just makes the game compelling to play, in essence the game is merely a vehicle for me and my friends to have a good time.
- The intellectual puzzle the game provides gives me hours of endless amusement, either a puzzle I must master on my own or a chance for me to grind my brain against an opponents till one of use emerges victorious.
- Or there is an element of prowess, either through hand eye coordination, effective use of real time strategy, or some other measurable skill that exists in the moment
(the main difference between 2 and 3 is the immediacy of 3. I'm allowed to mull over a move in Scrabble or a turn of Civilization for a long time, or at least until my opponent brains me. But I can't ponder the mysteries of a Zerg rush and live, its is a matter of skillful reaction.)
