I don't have much to say about this. It seems pretty straightforward and usable.
I suppose a few plot hooks would be helpful to get the imagination working, but I doubt it would take much to come up with something on my own. If you have a player really willing to get into the role, you could have them find it and play up the effects until the rest of the party realizes there's a problem and have to intervene.Go to Comment
Some interesting considerations. I was once on the player's side of the equation for most of a summer and I agree with what has been said. Game mechanics were mostly ignored in favor of heavier role-playing. I rarely interacted with more than one NPC at a time. I got myself into a few jams, similar to what has been described (no other players to reality check my ideas.) I was lucky to have a creative and forgiving GM.
Good article manfred. I especially liked ephe's idea about using solo gaming to warm up a group.
