Sony made no bones about where it stood with policies like not allowing used games, or requiring online connectivity to play games, as it revealed absolutely nothing would change from the way things work now when the PlayStation 4 arrives.
The PlayStation 4 will allow you to trade, borrow, lend, or give away whatever games you want. The person who gets the game after you faces no restrictions, just like they wouldn't on the PlayStation 3.
The same can be said for online digital rights management. Sony's PlayStation 4 will have none. You won't be required to be online to play a game at any time (unless it's an online multiplayer game, duh).
Those were two major shots fired across the bow of Microsoft, which installed such policies for the Xbox One. It's likely Microsoft is now rethinking those decisions.
With a lower price point, and no forced new policies consumers vehemently spoke out against, it would appear Sony has gained the upper hand on its competitor at just the right time.
