Also, A little off topic, but he has the beginner box, core rule book, beasteary pawns and museum map already. I would like to add to his collection for Christmas. Can you recommend some "bang for the buck" add ons? He seems to want more adventures? Are the cards a good additions? Thank you so much for helping this mom out!
The question of 'what would a 12 year old want?' had me thinking back many, many years ago when I started playing D&D. Some of my favorite reading material were adventure modules, any and all Monster Manuals and Dragon Magazine (too bad there is no more Dragon magazine).
If your son enjoys reading adventures and bestiarys I'll bet he will turn out to be a Game Master for many years to come.
