Thanks to Magma MK II and LaVey, both administrators of respectives Gradius Wiki and Castlevania/Contra Wiki, a Suikoden channel have been created for us on their Discord server. Thanks also to Milkandchocolate, the Discord is now directly accessible via Suikoden Wiki.
In the Discord Server, you can find many famous Konami games series, such as Castlevania, Gradius, Silent Hill, Contra, Parodius, Metal Gear, Goemon, Twin Bee and some mores, all have their proper channels to discuss about. And now Suikoden have also its own channel, so you can discuss anything related to the serie in it.
Feel free to give a go, if you feel like it. This is a nice place with a cool community!
