I gave in

[astramance]

I just:

1) purchased the core book of Ars Magica 5th edition although I already have the 2nd and the 3rd editions in various languages and that I had told myself that I wouldn't need more than the 24 Ars Magica books I already have

and

2) joined a forum to play an Ars Magica saga online

.....

bad, bad Astramance...
