Legacy is a good old fashioned web RPG. Like CB here, it shines because of its community. Granted, there are many players who I'm quite shocked are even capable of breathing, but that's besides the point.

I believe CB could learn a thing or two from the game. I'm sure it must have *some* idea worth borrowing. (For example, I like how system notifications and mail are handled differently, but I guess it's a matter of preference.)
