I pretty much only bought and owned a PS3 for many year just because of the Uncharted series. The last year or so I've started playing a lot of other games on my PS3, and even bought a second one, but I'd say owning a console is worth it for one good Exclusive. That's pretty much why I buy every console that comes out. All of them will end up having something I want to play that's Exclusive to it.
Now Playing: Mass Effect (PS3) - Batman: Arkham City (PS3) - Uncharted: Golden Abyss (Vita) - The Walking Dead (PS3)
