I like the element of randomness. I hate knowing that every time I lose it isn't because they were better than me, it's because I didn't try hard enough. I play games to have fun, not to push myself to the limit every time. What precipitated my mostly giving up multiplayer was when I noticed I was forming my habits around winning and it was working. If my room lighting was good, if I drank coffee before a match, if I played during the right hours of the day, I won. When I started avoiding using the bathroom because having to pee made me more alert, I knew it wasn't worth it anymore. I like games, not sports.
