I don't think it'll hurt to show a couple screenshots. It's currently set up so it only loads people within your level; this helps to reduce lag on the overworld.
All throughout Graal City, and other released parts of the game, there are mass numbers of players (like you see here). They're a lot of fun, and some of them are actually really good at sparring & pking. :P
Things are turning out really well. I'm glad to see dedicated staff effort ending up so fruitful.
PS. The world probably looks so much bigger, and enveloping on an iPod.
