Exactly that, the looming and ominous atmospheres crafted by beauty that turns into malevolence or by putrid hatred are much more appealing to me than the generic fantasy tales that we have read myriads of times (for historical reference, myriads is like 10,000s since μύριοι in ancient Greek meant 10,000 and they used it to count soldiers in battalions or so).
I am with you, better to decrease the goal since you already reach a respectable amount of funding and then the effect of that into the backers' psychology will sprout even more backers and funding rather than going again for the big deal. Indeed, summer is usually dead, people allocating money for vacations rather than for gaming.
The initial mould cost is the biggest nail in the financial coffin but as you mentioned, following prints make it much more affordable, that is why small companies actually gain profit from second prints rather than the first investment. I am also intrigued to see the new ideas you have come up with, especially since they will be shrouded by your aesthetic and creative patterns.
For solo play I have no idea or feedback since I play board games to socialize with my group rather than embark on an adventure myself against the lore of the game. A final question is about your singing, were you the one singing in the thinning veil promo in instagram? I think it was a "Rainbow in The Dark" song but I did not recognise Dio in it. I am a big fan of progressive metal and rock, especially when jazz is added to the mix but of course I pledge allegiance to the older rock and hard rock gods.
Keep us updated please about your progress and brainstorming and eventually, we will enjoy all your vision and why not a novel as well?
