Suikoden 1 is "on the way" to PSN Europe and it is understood that Suikoden 2 will shortly follow.
but yes, there is currently no way of playing Suikoden 2 unless you have a old PSX and a copy of the game, which could cost you upwards of 200 quid.
I have a copy, the one I bought when it came out first. But it's flawed; the CG sequences break the game, and when they're finished the graphics are all messed.
I need to decipher the pixel squiggles to reach an Inn, Save, then reload the game before I'm away.
Suikoden 2 is coming to PSN? Great news. I'm going to download it from my US account the second it's, inevitably, released in the U.S. first.
