I couldn't believe my luck when Sin & Punishment was released, so what I am looking forward to most is the prospect of more shocking releases of that ilk, perhaps some localised Jp-only classics. For now though, it is considerably cheaper to take the modded Xbox route for your retro fix. I for one think that it is a bit cheeky to charge seperately for each of the Mario games on the NES, for example.
Saying this, if they released Demon's Crest I would be reaching straight for the credit card details, once I had finished a celebratory bout of onanism.
