All right, assuming I get a PSV (as PSTV seems not worth to me), what other games can I get on it? Persona 3 is a given, anything else?

What method of paying are you using? Credic Cards and PayPal are somewhat problematic, but prepaid cards should be OK. At least, I never had problems with PS3 and PS1 games. PS2 games are probably same too, but I never bought any.

But I'd need a US prepaid card to buy it online, wouldn't I? 

PS: I've tried using both a CC and Paypal, and they both fail. Especially in Paypal's case, I paid 10$, then Sony rejected the payment, and the order was cancelled.

Get a PlayStation TV. Cheaper than a VITA and compatible with Persona4G.

Yes, you need US cards. These can be bought on E-bay, for example.

Btw: if you are going for PS2 SMT games, then look at SMT: Nocturne (basically SMT III) and SMT: Digital Devil Saga (both I and II). Just saying.

Don't get a Playstation TV, just don't do it.

The only reason i'd buy one of those over a vita is for remote play with ps4.

Thanks for the input everyone, I have found a solution. I have purchased a US PSN card and used it on my PS3. Downloading now ^_^

PS: Will certainly look into a Vita down the road, once cheaper and more games have come to it. Thanks again!

Thanks man, just did that and worked like a charm. Will also look into the other SMT games you mentioned, as well as Soul Hackers and Devil Survivor 2 on 3DS. SMT might have just become my favorite series ever :D

Nah, it just doesn't seem worth to me either. I'll just get the PS2 version and look into the PSV later on.

Buy PSN codes on a specialized website, i guess sony doesn't let you finalize the transaction because you use an european credit card ?
