This is the first thing I've been able to find about the mysterious DriveClub PS+ edition. It's very odd that no one covered this yesterday or last night. Thanks for posting this, Patrick.
"We want everyone to know what's happening" is the most outrageous statement they could've made. If that was true we would've heard something yesterday. Not 24 hours later.
To be fair, they did announce this yesterday. GB was just slow on the news front.
Not that the communication was great anyway - it wasn't until after the other PSN+ games had gone live that they mentioned any of this. A lot of frustrated people were checking the store regularly in the hope that it had been unlocked. The whole thing was handled pretty poorly.
Sure, it's a huge free demo and that's nice, but expectations are key here. Don't tell people they're going to get something on a set day and then not update that information once it's no longer correct.
