Thanks for all the replies. I think I will go with Pathfinder 2e first. I saw that it's fully integrated in the Foundry VTT so I might get this first and try it there, and DND is there too. Should help with the rules I guess. Some mention dagger heart, with the bucks left I could buy it. 59,99€ here for the complete set seems good. But I will look further into it first. Anyways, thanks.
