If you have the US version of the game and buy the EU add-on you are stuck with a game that does not work. Sony support say its your fault and to suck it up. This would happen the other way around also.
My GF wanted the physical copy of the game. I couldn't find an EU version so I got a US version. Surely not a big deal, Playstation isn't limited by region DRM. Or... so I thought...
I assumed that because games worked anywhere addons would just work. I didn't even know there was more than one store. I thought there was just the PlayStation store. I assumed the only difference between being in different countries was the language and perhaps the availability of games. I mean. The Walking Dead is The Walking Dead no matter where you buy it right?
Well no.. no it isn't. Apparently there is a sheet of paper in games warning about this. I have never seen it. Apparently it is in the ToS for the store. I thought people didn't read those.
Contacted Sony Support about this honest mistake and was told tough. I thought owning PS3, Vita, PS+ and spending a several hundred pounds on games would make some sort of different. Apparently not. Cannot even be refunded with credit.
Trying to escalate the complaint but the support guy seemed confused about this so who knows.
So yeah. Be careful what version you buy.
