I see Carl and starcraft have already provided their input, and I agree with them for the most part. Though, this thread really escalated far more than it needed to, and the only thing I'll say about that is that you don't need to post in every thread; if you don't like the topic of discussion or the looks of a thread just move on and try another one.
Similarly I've got myself a copy of TLoU:R and it's excellent. Sure, it may not be needed, but it is wanted and the Sony fanbase are buying it and enjoying it, as are reviewers. Surely that is enough of a justification for the game to exsist, even if you yourself won't be buying it or see the point of it. Perhaps, then, the game isn't for you.
I'm not here to deny, however, that the game is a "cash-grab" or a cheap solution to an otherwise larger problem, because it is. Doesn't mean you can't enjoy it.
