I'm just mentioning it to show that difficulty is fun. :D

But Touhou is strategy too! :<
In a way. I guess. I just memorize everything.

But if we're talking about difficult RPGs I'll say that the Labyrinth of Touhou doujin dungeon crawlers are prettty difficult on their own anyhow. But we're getting off topic now.

ANYWAYS, looping back to the question earlier: No, everyone does not have to be in Akiba. Wherever in Japan in general is fine, really.
