I don't know actually if people will really care about how well other people do. As for ranking system, currently you guys only can compete who makes more money I guess.

Maybe who progress the fastest? But other than that, nothing else. Maybe later on, when I have a game more suitable for this idea.
It might be very interesting to see what other people's are currently doing, such as walking around, play what games, I agree. I always want to see "people" walking around the town. But that requires the whole game platform better migrates to MMO flash server. Which seems is a little bit too early for now. Maybe when this community grows to certain size.
Right now, I am just concentrating on making some more interesting individual games to keep you guys busy^_^. I think I will need couple of more games at least.
