Ars Magica is the coolest tabletop game ever made. There is absolutely nothing that comes even remotely close to it in terms of pure wizard fantasy. Making my own spells and magic items has been some of the most fun I've ever had at the table. I don't know if I can ever go back to generic level ups and set abilities.

Why does nobody play this game? I've never seen anyone here even mention it before. All you have to do is read the book. Even if you don't like the setting it doesn't seem hard to adapt to whatever sort of world you want.
