Moreover, it is confirmed that the sequel which will be released soon is going to include an updated version of the original game, making the localization of this title a nice opportunity and a good reason to have skipped the first SK. http://andriasang.com/con17e/senran_kag ... st_update/
I even wonder if this wasn't done with international audiences in mind, as the director wasn't against the idea of exporting the game.
Some advised a double pack earlier, it seems that they were prophetic about that. XD
