As you can see while the US release is vastly different from the Japan release there is a huge difference in terms of the amount of Sega CD games and the amount of RPG and classic games on the Sega CD such as the Lunar series, Popful Mail, and missed out on releasing such other games such as Snatcher, Flink, Keio Flying Squadron, Lords of Thunder, and The Terminator.

Will I get the mini 2, maybe but it would be the Japanese version due to the more games I want to play than what they have on the US version.
