Well, sometimes it's also down to luck in completing 2-4.
That random compass way sometimes really makes me pissed off especially if she sent me into the north abyss of 2-4...
Regarding the localization. The game itself not really on level of international popular. Maybe in the future after the Vita game, merchandise and anime comes out. Kancolle are still appealing to anime fans only, not on general gaming fans.
And the second one, this game is released as a part of DMM website. DMM have an adult section which may not sits well with some other country regarding their pornography section.
Basically it is still a risky move by Kadokawa to bet on Kancolle, though their bet seems pay off.
Now back to grinding Mutsu...
