I burned through all Delve content in a few nights, and immediately applied it to my first session. Even coming in for the first time, these new rules complemented the Core content so well that I couldn’t imagine playing without it (and I don’t have to now! Woo!) If you enjoy base Ironsworn, or are hoping to try it for the first time, my first suggestion would be: Pick. Up. Delve. The new features & rules expand the setting in a meaningful way and only add to the experience. I’m quite satisfied with my PDF purchase, but am planning on a hardback cover soon (also very cheep!). So if you’re on the fence about getting it, all I can say is DO IT.
