Most of these but not all were very popular in Japan and have big libraries over there. Often great games. In systems like TG16, Saturn, Dreamcast, Neo Geo Pocket, SMS and Vita a small portion of their games made it west while the rest and mostly best games are in Japan. Saturn has well over 600 games overall. Dreamcast 700 officially. Only 248 of them made it to the US and 219 in PAL. These systems with a couple exceptions just had hundreds of great games but sadly stuck in Japan.
