I think this Is a GREAT Idea! I'll let the owner, Darkfire, Know about this, and, with any luck, he might be able to make something along the lines of a GWD (God Wars Dungeon). The only problem is, If the GWD NPCs (Non-Player Characters, Ie: A level 2 man) Aren't already added into the WebClient's Model folders, then you won't be able to see them on the webclient. (they'll either appear as another NPC, or be invisible.) These NPCs WOULD be added to a DownLoadable Client, which can run quite a bit faster than the webclient. But the only bad thing is, players don't like downloading clients. I dunno why- since they're so much better, and safer, than webclients!
Oh well, we'll see what we can do. This is a great idea, and IT WOULD help the server gain more players as you stated.
I enjoy hearing feedback from you, especially Suggestions to make our server(s) better.
Keep up the great work, and keep posting Suggestions, we need them!
