Valve often talks about trying to provide a service that is more convenient than pirating, and this looks like another step in that direction. If I'm playing a pirated game and want to share it with a friend, it would involve getting them to torrent/crack it, or uploading it to a file sharing host. Using Valve's new program, sharing a purchased game is as simple as sharing it with them on steam. I'm curious as to wha…
Most old popular games come with a .exe that you can run without installing the game. Make for some real easy sharing in Lans. Valve making it almost as easy.
I know back in the day half my friends ended up buying copies of Starcraft because they'd done a multiplayer install at a LAN party.
