I don't necessarily understand the point of having a NSFW card game, when the rest of the game doesn't really benefit from its existence. Feels like a sort of afterthought, or an idea shoehorned in, in order to appeal more to furries and drive ratings/downloads.
Anyway, the concept of building your own empire/city with Rust-styled gameplay is pretty interesting in its own right. I can tell you're a fan of games like AoE and such, but of course you don't get to build things hands-on in those games. If this gets developed further I could see it becoming really fun, but I'm sort of iffy on the NSFW porn aspect as that'll severely limit the game's overall audience. Either way, good luck!
