The main Heroica set Castle Fortaan (#3860) is on offer at both Amazon.co.uk and Amazon.com
If you were thinking of buying a set pre-Christmas, now may be as good a time as any.
I recently received review samples of two of the smaller sets from Lego, and I have been playtesting them for a review which will appear in the next issue of Oubliette. Both of the games I have played have been great fun, and my five-year-old daughter is now routinely picking up the box sets and demanding a game. It is a fait accompli that she will find the other two sets in the range under the Christmas tree this year, and I am looking forward to playing with all four sets linked together, even if the likelihood is high that she'll thrash me.
