If I already have Arcana Unearthed, do I have to buy Arcana Evolved?

No. Arcana Unearthed is still a great game, and as I previously mentioned, the two books are fully compatible. But it all goes back to what I was saying about more.

If you re an Arcana Unearthed player and you crave more more of everything that is Arcana Unearthed, really and you want to have all this material in a full-color, complete volume, you re going to want to get Arcana Evolved. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
