We should try to get this series on Steam/PC platform. The first two games, especially, are some of the greatest character action games in existence. I've checked and haven't seen any other mention of a petition on here, so I've created one to let Koei Tecmo know of my interest. If there are any other of you out there and you'd like to see these kickass games on the service, then sign and let them know.
It's always better to be heard when it comes to these things.
