why not just IF one person e.g. stoner downloads the updates and the distributes the gcf to anyone that needs the update
I almost always have the latest versions (since I'm almost 100% legit these days), but we don't get installers afaik when we dl the newer versions, and copying over the entire game folder will take ages - assuming it even works, since last time I tried it didn't.
Making a Steam backup of the game, then distributing that may work. But making backups of every multiplayer game I've got will take a while.. and then there's the typical problem of ALMOST NO BODY EVEN HAVING THE GAMES LEGIT.. so there goes that idea.
