Even if "so many" were a meaningful amount (I'm not convinced they're much more than a noisy minority), this "Screw you, I got mine" approach does nothing for drawing in and keeping new players. As it stands, Square-Enix is at least pretending to want new players, or else they wouldn't be selling the Ultimate Collection to begin with*.
* Unless we're talking about Japanese Xbox 360 players, then yeah: they don't want new players.
