Fire Emblem is a good example. They were very popular in Japan in the 90s, enough so that Smash Bros. Melee (2001) included 2 characters (Marth and Roy), yet the first Fire Emblem game to come to the US was a GBA game in 2003. Now Fire Emblem is incredibly popular in the west.
Monster Hunter also comes to mind. Before Monster Hunter World, main series Monster Hunter games were on Nintendo’s portable gaming consoles, namely the DS and 3DS, because those portable consoles were very popular in Japan. Once Capcom brought the series to the main consoles with Monster Hunter World it became a huge success.
A Leningrad pun, yes.
