It'd be interesting to consider whether it would have gained the same success and positive inter-user recommendations had this been enforced at launch. We can already see that users now have varying reasons for their distaste of the enforcement:Just as a reminder, since Reddit seems to be going apoplectic, the store page has always said the game requires a PSN account.
- PSN not available in their region. Affecting quite a number of users. Xbox online accounts said to have far better worldwide availability than Playstation.
- Against the inconvenience or principal of creating a separate account for a game that was functioning without it, not to mention on a console network when they're PC players.
- Against the added potential security/privacy exposure of having their details in yet another database, with all the breaches that occur (there's a Reddit sub-discussion about this right now).
- Not wanting to tie one identity to another even if they have an existing PSN account (see a user here who expressed such).
OTOH from their announcement Sony's reasoning is a moderation-based one. I'm not familiar with how much of a problem this has been since I've only read about positive experiences.
