Check and see what you paid to make sure you didn't buy the $50 version. If you only paid the $10, considering yourself fortunate to have a good upgrade!
ninja edit: actually, it may have been if you already owned the Deluxe version that it simply upgraded you to it flat out on the store, since you only had to add to library. It's definitely not supposed wot work like that but hey.
Already did check via the emails you automatically get.
Tony Hawk's™ Pro Skater™ 1 + 2 - Cross-Gen Deluxe Bundle (Demo) $10.00 (this morning)
Tony Hawk's™ Pro Skater™ 1 + 2 - Cross-Gen Deluxe Bundle (Game) $0.00 (a couple hours ago)
I think there was/is some weird glitch on the website, which is where I added the Game to my Library. the upgrade I did on the console. Maybe the license will get revoked? If that's even applicable.
Edit: I did not own any kind of digital anything. Merely the standard PS4 disc. Which I bought for $17, actually, pre-owned from GameFly.
