who can easily explain what steam is? MW3 runs on "steam" - what is it? what does it do for me? tips tricks?
It is a damn annoying delivery system for games/updates/extras/etc. And it doesn't really do anything for you but some games are only available on steam so you are arsed out if you want to play that game.
Sure it does. It keeps you from having to purchase, store, and maintain your software, keeps games auto-updated, safely stores your gaming library indefinitely, generally has unobtrusive anti-piracy built in (except for GFW crap), and has the best prices in the industry during their seasonal sales. Really, no other similar service comes close.
