Being a good fan of The Touhou Project, and Serious Sam, I have the simple idea of a Touhou character player model workshop mod. Or modpack of a bunch of characters (all characters if not impossible or to tedious to make.) Like the Killing Floor Touhou project mods done by Shroom. Though i have zero knowhow about any model, or mod making.
I love the player model mods done by Pan and his friends (Serious Fantasy Legends packs.) Although i dont wish to bug them, for they may not be Touhou fans, and they probably get requests up the arse. So id rather post a long paragraphed discussion that probably wont get any attention, in hopes that someone might have interest in taking on such a project. Pardon me if i did a poor job doing so.
