Kickstarter, and "professionally" I'm not one to usually push a project unless it resonates just right. IIRC correctly I've only promoted the Reaper Bones Kickstarter because that was a great deal for GMs and it could only make getting cheaper minis easier down the line.
I've reviewed a couple of products from Small Niche Games (or are about to....I tend to work ahead on some entries) and while they were all geared at Labyrinth Lord for the underlying game system, I've found them all quite useful for conversion to just about any Fantasy Role Playing Game.
Yesterday I discovered that SNG has a modest Kickstarter for an upcoming City Guidebook. As of this post, the project is already funded, but any more funds are intended to be used to add extra/better art.
The cool part is that this project will be made available to everyone using DriveThruRPG's Pay What You Want Program. If stretch goals are made then there will be some additional product made available at a reasonable cost, or free for certain donation levels.
This is the kind of Kickstarter I can get behind and it seems like a win-win for everyone.
