Ok so...
Hot Shots Golf. I want to play online. I clicked "Online"...
Game: You need an online ticket, homie.
Me: This thing that says "Online Ticket" in my box insert? Gotcha.
Game: K, enter it at the PSN Store.
Me: Will do.
*Opens PSN Store*
*Hits Ellipses, which brings up the menu "Enter Online Play Ticket Code*
*Does*
PSN: So you wanna play Hot Shots Golf 6 Online?
Me: Yep

PSN: Cool, here.
Me: *Opens game again, selects Online Play*
Game: You need an online ticket, homie.
Me: I went to the store and I...I did that though?
Game: You need an online ticket, homie.
Me:

*Back to the PSN store, enters in same code*
PSN: Code's been used, buddy. Wanna buy one for 900 yen?
Me: Ffffffuuuuuuuuuuuu
So what just happened? I punched in my code at what seemed like the right place. Game is cockblocking me, PSN is pretending nothing ever happened.
What I am noticing is that before, I didn't even see the option to BUY a new code. So was my code (brand new copy mind you) just like...a code to buy a new code? That surely can't be a thing.
