Quite disappointed that his is a mere remake of the original, but will very likely get it anyway.
When I had my PSP, I played all of the 'blockbuster' titles including Final Fantasy, God of War, Grand Theft Auto and numerous others, but none came even close to this gem - funny, interesting, charming and brings some truly amazing innovations and gameplay mechanics to a genre that IMO was becoming quite stale, just in the same way Call of Cthulhu did.
I recommend without reservation that anyone slightly interested in this game checks out the demo at the very least, it's definitely worth your money, and your time!
