Like some others, I'm fiddling with some homebrewed games using the EtoE system. I think the biggest hiccup I'm hitting so far is how to plot out a new Talent Tree. Not the abilities themselves so much, but the connections between them. Some of the published ones are pretty straightforward, while others are... Okay, I'm gonna say it: the path through the Slicer tree feels almost sadistic. For those who have built their own trees, do you have some pointers for a new guy?
Also, I would like to commend FFG for making a system good enough that I actually want to convert other games to it. I'm a huge Savage Worlds fan, and while enjoy plenty of other games, I always found myself thinking, "I wonder how this would work with Savage Worlds rules." That this system is solid and flexible enough that it offers competition in that arena speaks volumes about it's quality.
