Two weeks ago, Apple crushed some gamers' dreams by rejecting the Steam Link app for iOS, which would have allowed users to stream games from their beefy computers to an iPhone or iPad. 

But today, it's looking like the Steam Link iOS app might have a real chance of being approved -- because Valve has unceremoniously ripped the Steam Store out of the experience. That leaves gamers with no way to buy Steam games through their iPhone or iPad, but it also means the app no longer breaks Apple's App Store rules.
