Reminds me of this:
(aka "Fears of a software developer")
There is definitely some truth to that kind of reaction but as is often the case with fears, they are not all that helpful and largely irrational.
This doesn't just apply to us but to anyone creating anything. It's normal that, as soon as you start your project, you will pay more attention to things that appear similar. Suddenly your idea is everywhere where before it seemed wholly original. There are a bunch of cognitive biases that further intensify this: attentional bias and frequency illusion are probably the most relevant.
We weren't aware of any tavern sim games before we started work on Tavern Keeper but since then quite a number of games with this overall theme have popped up:
Moonstone Tavern (was previoulsy Fortune's Tavern)
as well as a whole bunch of free to play, mobile and flash games...
So, why would we bother to invest so much time, money and energy into an idea that doesn't seem all that original anymore?
Simply put, while the idea of a 'tavern simulation game' is not unique, our vision for that game, and our execution of that vision is. We believe that Tavern Keeper will be something special and we are looking forward to showing players why.
We don't really see these other games as competition. Sure, they share the same theme but from what we see our game will be quite different. It's the same story with Game Dev Tycoon. There are now a bunch of game dev simulation games but we don't see this as a bad thing.
