I think a lot of what was said in this article can be applied to other competitive player verse player games. There was a time where I had gotten Legend of Zelda: Link to the Past for the GBA, mostly because I just wanted to play Link to the Past again. It being the GBA version, it came with the Four Swords Adventure game, which you could play with up to four different people. My brother and I had decided to give this game a try and it was kind of interesting, up until he pick up my character and started to take most of the treasures for himself. The game stopped being fun to either of us because it turn into a competition where we were in the game to win for ourselves, with my brother being the main winner because he was more used to performing tricks that would undermine my progress. So ever sense, I never really cared so much for games with competitive features in them, as I would like to play a game for fun and not to prove myself better than someone else. I'll be able to do that once I find out what my talent is...
Off topic, I wonder if it is just a coincidence that I got the Spy vs Spy: The Complete Casebook not too long ago.
