If Mario Party desyncs on my 7mbps connection, CC would have several different kind of fits at once every few milliseconds.

Ok, first off, lemme tell you something. An RTS is ridiculously easy to keep track of all the units and bullets on a computer (WH40K: DoW: Soulstorm being a 3d realistic RTS). The difficulty shifts up a bit when you make it netplay-compatible, but it's still well within the limits of convenient. In fact, I believe the genre RTS was the first game played over the internet, being Chess.
Now here's what kind of information we deal with in CC and how easy it is to transmit over teh interwebs:
1. Player input, mouseclicks and whatnot: Simple. And there's only one every half a second or so (not always the same rate, so on average.) So perhaps one keycode every half second to be sent. 2 numbers per second.
2. Object/attachment position/wounds, where actor pieces are: Simple, there's really only a few values for each piece, X, Y, rotation, and damage values. But, there's quite a few on the map at once, perhaps a hundred or two. That's like 4 numbers that have to be updated for a hundred objects every frame. 30 fps is considered the standard "good speed" for a game to run at. 4 x 30 x 100 is a rather large number, and you have to send probably 32 bits for each number (not a network person).
3. PIXEL PHYSICS CALCULATIONS... Simple in theory, sure. After all, it's just a pixel. All it does is move according to a velocity by changing x/y every frame, then comes to rest when on the ground and velocity is close to 0. So, about 4 numbers per pixel too. Now, since CC is such and incredibly detailed game and every pixel is both destructible and movable, all active pixels have those 4 numbers to be updated every frame. How many pixels are there active in a typical CC match every frame? I'd say a low bid for the average is about 5000. And that's without mods. So again, 4 x 30 x 200 numbers per second. Add that to out current running total ( 2 + ( 4 x 30 x 100 ) + ( 4 x 30 x 5000 )) and you get 612002 numbers per second. Now I don't know how Data handles these numbers(bittage wise), but I'll take a safe bet and say about half are 16, the other have a split between 8 and 32. So let's do that. ( 306001 x 16 ) + ( 153001 x 8 ) + ( 153000 x 32 ) = 11016024 bps. That's a lot. Without changing that into packets to be transmitted over teh interwebs, thats 10mbps, or about 30% more than my connection can handle, and I have the fastest connection my cable company offers.
Bah, it's almost a waste to repeat this argument...
