Apparently, there seems to be a Japanese DRxTouhou fangame out there too: http://1st.geocities.jp/crawfordproject/c_pro_g020.html
Anyway, if I understand this right, you're aiming to put in Touhous that fit the same roles as DR1's cast? Is the plot going to be similar too, or do you plan on taking that in a different direction?
On a maybe more important note, how different is this going to be from the DRxTouhou Youtube videos you're watching? I noticed you talking about the characters using cards - I don't know much about that video series, but they're doing the same thing too, right?
Someone already beat me to it?! Ahh... I'm feeling happy but depressed at the same time... I admit that it looks really good, interesting and would seem fun to play, but it seems like the creator threw some of the characters in there for the hell of it, or just put placed them in there because they popular Touhou characters or something else?
Anyways yeah that's the plan, I want my Touhou x DR project to have characters to fit the roles of the DR characters. Someone did suggest a idea of forcusing on popular characters, but as you see I declined as I want lesser popular characters (That would fit DR chara's) in a staring role.
Hence
Sanae - Naegi
Kasodani - Sayaka
Nitori - Chihiro
Mokou - Mondo
etc
I plan on taking the entire plot on a similar route but not completely the same. I was thinking of having the deaths somewhat differently~ The only similar thing that this project and the video series will have is the cards system. In the video the people trapped inside the school can use their abilites such as unconicousness where Koishi cannot be detected and can use it as much as she wants. Where else in this one they will only be able to use their ability once.
A example would be that Mokou has the Phoenix Card, she gets stabbed by lets say Kaguya and dies. Her card automcally actives, therefore giving her a 2nd life. Mokou freaks out with a weapon in hand and kills Kaguya in some way. That's how I want the card ability to work, that the user can only use their ability once and that's it.
Anyways it seems the Touhou community will have a Western Touhou x DR in an AU and Japanese Touhou x DR in Gensokyo. xD Can't wait~
