Sure, playing games can be fun, but there I have the luxury of competing against myself more than anything. Can I play better than I did last time? Did my skills improve? Have I learned to trust my instincts more? I don't need artificial pressure. If I'm not willing to try my best to win, the activity is probably not engaging enough for me to bother with. Not everyone approaches games or recreational competition the same way, or gets the same things out of it. That doesn't make us sticks in the mud, just not you.
