Namco Bandai has tweeted its Japanese followers asking for suggestions about which PSone and PC Engine games it should consider bringing to PSN.
Namco already has two PSone games on PSN - Mr Driller and Tekken 2 were both released in Japan in late 2006, with the latter hitting US the same year.
Any old favourites you'd like to see? Ridge Racer Type 4 would be top of our list, followed by Klonoa and the Tales RPG titles. Mobygames has a handy list of PSone possibilities.
