Kheldon writes to point out an interview with David Chang of GamesCampus about the up-and-coming sports MMO genre. He also talks about their efforts to bring older demographics into gaming. Quoting: "One of the things about the baseball game in particular that's so great is that there is a leveling component, not just to the team, but also to players. So you're exactly right in terms of the persistence. We want people to not just play a baseball game, but ... to grow their team and their players over time. So, there are things where if you win a game, that's how you gain experience points. If you win against a higher level opponent, you get more experience points; if you bottom feed and you take advantage of lower-level players, you don't get as much, and so on. There are a lot of MMO-type concepts in the game. If you're talking about individual players, if you hit a lot of homeruns, or if you steal a lot of bases, your power or your stealing stat will increase over each season."
