I’m not really into trains but I’ve always been a fan of the Densha de Go (電車でGO) series. The games are train simulators using real routes in Japan and real trains. They might appeal to anyone who has enjoyed recent titles like Euro Truck Simulator. The series has featured in arcades, home consoles, and portable systems including the Japan-exclusive Bandai WonderSwan.
I’ve recently been translating WonderSwan game manuals for people online and have decided to post some here and form a library of sorts. If you follow the Translations link in the website’s menu you can navigate to translation including one for the WonderSwan version of Densha de Go.
