A meta-example (I've gone through three times in the last month); a friend and I were playing Halo 2 at another friend's house; we were playing it split screen, and having fun doing it. Guy who owned the Xbox said, "Hey, why don't you play online, it's great!" So we did. "We didn't like it" would be a bit of an understatement; Mike walked away about five minutes in, Zeb stopped playing five minutes after that. I went for a second round, but quit halfway through.
Now what bothered me was they didn't seem to be enjoying playing, but were playing the game for the sake of playing the game. Then again, there's a good chance I completely missed the point, and all it is is a giant dick waving contest.
Apologies to Halo fans, but I liked Metroid Prime better anyway.
