I played the game without a PSN account, along with most of the HD2 community, and I was happy with the content, which in no way relied on having a PSN account. I don't have one. I played the game. Therefore, it was not required, regardless of what the store blurb said. I got exactly one notice to link a PSN account, which I skipped, it was a skippable thing, meaning was not required. When I skipped the PSN account, it took me straight to the game. There was no notice that it would be required to link at a later date.

If no one has told you yet, you have an amazing tongue. Your capability to lick boots and kiss ass is unparalleled. Shame that Sony won't notice your efforts here either.
