Its always nice to see another Dane interested in otaku culture
I've in fact already dabbled in a few hiragana courses, not that i learned much.
I really enjoyed G-Senjou no Maou which has probably been my favourite for a while although Hoshizora no Memoria is also high up there. Lately i'd say the Muv Luv series has been my favourite, im going through my first playthrough of Alternative right now and gotta say i really enjoy the setting.
