Kumada, have you considered approaching Free League for Cthork Borg?  They just worked with an independent creator to produce/distribute Pirate Borg…

I think they might be a bit out of my league. Pirate Borg made  160k on kickstarter, and most of my crowdfunds have done about 5k. I could try to crowdfund some Cthork content, though, and if it gets big enough I could try to approach them.


Don’t sell yourself short, my friend.  The fact that you have a fully realized Cthulhu game that’s fully compatible with Mork Borg and Pirate Borg might be very attractive to Free League if they are looking to expand the “Morkverse.”  It never hurts to ask them, you never know!  🙂

Oh, I like Cthork Borg. I've enjoyed developing it so far and I plan to develop it further. But I think a large publisher's biggest concern is going to be profitability. Once I get that down, I may try reaching out to bigger presses.


Well I think Cthork Borg is fantastic and takes the sturdy Mork Borg rules platform into exciting new genre territory.  


have you ever run any cthulhu adventures in this system?

I tested out the Cthonversion Kit by running Mister Corbitt, and it went pretty smoothly.

Adventures from systems like Cthulhu Dark or Delta Green might be a little less smooth, since their mechanics expect different things from play.
