I'm no longer a victim of "new shiny", thankfully I got that out of my system when I realized just how much stuff I had for AD&D 2E. By coincidence, I happened to randomly open to Grenade-like attacks when I was looking for something else. Again, I'm appreciating how much simpler HARP is compared to other systems.
Yes, there are books I'm waiting for, and Bestiary is one of them. I have one RPG that has had no updates in 13 years, though the son of the authors is old enough to be interested, and there has been word of a sourcebook in the works. As the RPG in question, World Tree, is a labor of love, it'll get done when it gets done. Just like the partial fursuit I'm making.
