Ever hated the ending in Kanon where Nayuki loses to Ayu despite the fact that Ayu was in a coma all this time and is a ghost? Always wanted to beat up Shion with Akari from To Heart? Always thought the main character made a bad choice hooking up one of the 9 possible chics going for him in those 'soft' anime you watched?
I ask you, ARE you a die hard anime fan who has supported the another girl only to be disappointed?
For bishoujo anime game fans out there, a great man, Watanbe Sajsomething has revolutionalised anime and 2d fighters.
'Soft' anime (ie. To heart, Kanon, Comic Party) mostly based from bishoujo games have been made into a 2d fighters, with all the characters you know and love who can now beat the living crap out of each other. The grapfics are pretty good and the games are pretty damn popular.
A couple of titles are: Queen Of Hearts 99 - Mostly using characters from the anime 'To Heart'. *Akari uses kitchen utensils! BOO YEAH!*
Eternal Fighter Zero- Kanon characters
And Queen of Hearts 2001 Party Breaker includes To Heart and Comic Party characters.
This is one of the most enjoyable 2d fighters you will EVER find. And no this isn't one of those amateur games made by amateurs for fans, these games are lisenced, well close to it, and are made by people with experience, dedicated to the loyal slaves of anime.
