Screw it! Give me Guilty Gear x Reverse 1999
Exactly what it says on the tin! People were talking about crossovers when the AC one was announced. It just came to me the other day, I want Guilty Gear in Reverse. It makes weird sense since all technology runs on magic there, they've got a culturally diverse cast from all over the world and there's all the weird shit we love about Reverse. Ghosts? Zappa (I think that's his name, I started with Strive) Aliens? I think the Valentines count. Vampires? You want dandy man or black cyborg ninja one?
So, what's your out of pocket crossover that weirdly makes sense?
