Thanks for the interest guys.
I currently plan to fund this on my own, without Kickstarter. I am currently speaking with a few artists and have an idea of what my art budget will be. Still need an editor and am considering having someone other than me do layout. That's extremely time consuming. End product will be PDF and POD, though I may order a stock of print copies for myself, cons and such.
I got into a brief discussion on comparisons to Silent Legions on G+ yesterday and here was my answer: "I can't compare ET to Silent Legions, as I have no experience with that game. However, I can say the Eldritch Tales will put a game on the table that is designed to run adventures set in any era, that is meant to work with other White Box games seamlessly, and that will include rules that can be hacked out and used in other OSR games.
Additionally, I plan to support it in a number of ways - era books, for playing in a variety of time periods, and adventures, to start. More importantly I will produce a compatibility license that will allow third-party publishers to create their own material.
I'm not sure how that stacks up against Silent Legions or other Mythos-type games, but I hope it sparks your interest and that of others in the community. Cheers!"
From that discussion it sounds like the games will be relatively similar, but there will certainly be some differences in mechanics. I also have no experience with Black Books... I totally missed that one. I'll have to grab it and have a look.
