If you are reading this review to help you decide whether or not to purchase Index Card RPG (Volume1, Volume2, new Volume3, Core Rules) just buy them!
The Runehammer ICRPG is great for inspiration and getting started quickly. If you are pressed for time and rarely play RPG's because you just do not have time to get ready, dive in! Index Card Vol.1 and the rest will give you both inspiration and confidence to play NOW!
Do not wait! Get it! Download! Print it out!
Play NOW! Do not over think (as I have for so long it hurts). I have lost years not playing because I do not have time for D&D or other games. However, after purchasing ICRPG and Index Card Vol.1, I got to play. And I can just stay "Let's play now!" without spending a lot of time preparing.
This RPG style will free you to play NOW! It inspires you and makes it easy to get started.
