Hi Skylabh,
Yeah, I like a lot Nightmare Creatures especially the first one and was thinking a while ago to write some tools for it like 3D level viewer or 3D character viewer but at the time I didn't had enough experience to do so but now I think I have, so yes I have plans for the Nightmare Creatures, it's just that right now I don't have free time cause any free time I have I spend on RE2RDTE and I don't really know how long it will take. The only thing I can promise is that with the first chance I will try to do some tool/s for the game
