Spends a lot of time at home. By himself. Playing with himself. Until he asks if you want to see his pokeballs, he's usually harmless.
Finally, and finally on topic, are the soloists. Online happens occasionally with this group, but more often than not they stay home alone playing exclusively with themselves. Does this make them less of a person then those who go out and randomly hook up to play? No, and in fact the soloist oftentimes has different and better experiences than those who go out to the same game over and over again. There's more games out there than the popular game of the month, you know, and being a solo player means that you're more willing to get out and try the older, not so pretty games, then being a slavish follower of the new sexy of the month.
Being willing to take a chance on a game that only you will play is also freeing, as you don't necessarily
have to tell anyone about it. Some people reading have games like this, secret obsessions that no one will ever hear about, but they can't stop playing and won't as long as they're not found out. You can experiment with different styles and different techniques, and if you aren't doing good with one type, you can always switch back to how you were doing it before. Also, not having to rely on someone else to even show up can be nice, as there's also no chance of you standing yourself up. You can play with yourself early in the morning, all through the night, and even right after lunch on Sunday. No one can tell you no.
So, is playing with yourself more fun than messing around with others? Depending on the circumstances, I believe it can be, as you don't have to wait for anyone, the only person you have to please is yourself, and the amount of enjoyment you get out of the experience is up to you.
