Ah, I see. That's a shame, I've heard the PSP version is quite good! Which one did you play? Freedom / Freedom Ultimate? With any luck you'll be able to get yourself a new one in time though! I'm fairly certain MHonline isn't even released yet and will only be available in China, like you said. Sucks cause it looks real cool.
I've been playing on my 3DS, though I'm not sure if MHX will be coming out on the Wii or any other system. Either way, I am very excited to play it and if you do get a system that can play it, let me know! We can go hunting together. :)
