You can lend your friends a console disc. You can not lend them a game you buy on Steam. Or at least, you haven’t been able to previously. That might soon be about to change. Some code buried in the latest Steam client beta , first spotted by NeoGAF poster Grief.exe but which I can also see in my directory, has revealed the presence of something called a “shared game library”. For three lines of code, that seems to present a pretty clear plan: you can let other Steam users “borrow” your games, then take them back whenever it suits. As it stands, right now once you buy a Steam game that’s it. It’s yours, tied to your account, and you can’t trade it in, sell it or lend it like you could a physical console game. Letting PC gamers share their games, then, would be amazing, though how Valve is selling this to publishers I have no idea. Maybe every single full game can now be its own demo as well?
