Oh no worries, I'm always glad to hear ideas, though obviously I have to turn down most of them. This is actually an interesting idea, and one I hadn't considered. I tend to take a chuckling, self-effacing view to the idea of merch for the games for the most part: a. Are people really THAT enthusiastic and b. Do they really want to advertise in public that they're jerkin' it to a cartoon bunny? But a poster would be...somewhat private? And fairly cheap and easy to contract production for, shipping etc, with some decent room for profit margin (sounds mercenary, but you have to understand this stuff takes time, and I'm running a business, so it has to generate at least SOME income to justify itself.)
So yeah, I actually really like that idea. That said: Time. I am currently working on the third Content Pack, and getting some IRL stuff sorted. After that I have to immediately dive into Chapter 3, giving it 150% of my time and energy because 1 was important, 2 was important, but 3 is also very important to get just right for a variety of reasons. Without even researching it I'm guessing it'll take me two to three weeks to whip up the art, and probably at least another month to get all the logistics of printing and ordering worked out. So it's probably not happening until after the initial release of 3 is out. That said, if you or others have suggestions for services to work with on this, I'll definitely archive them for reference later. Those kind of groups have a history of being unreliable, disrespectful of IP, and cutting pretty aggressively into profit, but it definitely won't hurt to get a jump on researching the options.
