I own a PC so I don't really care about my ps4, but it's really good, like really really good if it clicks for you which it did for me. If the final game is as consistent as the Alpha/Beta likely the best FPS of the last few years. Pretty sure the Alpha thread impressions were 90%+ positive after the poll.
That's a tall statement considering quality FPS games have seen a resurgence as of late.
Yes, it's good. The second question is a bit weird though...
If it's a game they like, what's wrong with justifying the purchase?
Many people find it difficult to separate their opinions from their need to justify money they have spent. The issues compounds itself as the dollar amount grows higher.
You often see it when people have spent a great deal of money on what many would consider an objectively sub-par product, Alienware, headsets, Beats, etc.
