While all these would be well and good for this game, they aren\'t probable. The servers are half the problem. Something like this would require a huge amount of space, and fast servers, to relay to people at a decent speed. This is possible in this day and age, just not for a free game. It would be a monthly fee type deal to afford the servers necessary to run this sort of stuff.

If you want something like what you are talking about check out Dark and Light, that may tickle your fancy.

The client based part is also right. Some people that want to play may not be able to afford god awsome computers, or have access to them in their area.
