ccording to Schneider, said super slow connections are what prompted the region blocking. Using a deterministic (peer-to-peer) network model enables the game's synchronized gameplay animation, but requires parity on both systems. If a slow connection is thrown into the mix, "the person with the worst connection brings down the whole group to his/her worst connection level," explained Schneider. "While not generally a problem for COOP (since most people play coop with friends) when playing in Versus mode 3 people can be highly adversely affected by one player with a bad connection. We use the region lock to minimize the likelihood of this occurring."
