If the success of video game GM modes, and Capgeek, and fantasy hockey, are any indication, quite a lot of people find drafting, developing, building, trading, signing FAs, scouring the waiver wire, and other personnel moves extremely interesting.
Think about it, when you play video games, or participate in fantasy sports, is the actual game play the funnest part? Or is it all the stuff you do in the lead up to the season, or the game, what's satisfying?
I tried to tell myself I liked playing the games but I soon found myself simming more and more games until I was just simming the whole season and concentrated on building my roster.
I think the games got repetitive after a while while building didn't.
