That's totally fair. I think the main system provides a heavy dose of what people associate with DnD, which is rolling dice, adding them to something and shouting out a number and then it's either big (yay!) or small (oh no!) without having to think about it any more than that. But we understand the subjectivity, and really tried to make the content as portable between game systems as we could.
I'm still curious to hear others try out combat. I know it's a wild claim, but I think our combat systems is genuinely kind of next-level. I know that sounds totally braggadocios to say, but I really think there's something there.
