And even if we accept that it was always intended to be PSN-only and they decided to launch before PSN integration was done, the fact that multiplayer is entirely dependent on them providing a service is troubling. That’s how we lose games.
I can still launch Rainbow Six 3 and play multiplayer with my friends because it has the server built in and allows direct connect via IP address. You can’t do that with a live service game; once the official servers are down the game becomes (partially or completely) lost media.
