redsales: Of course there are people who want to play with a lot of new pieces. This is also for me, but I think that some pieces are quite difficult to understand and also difficult to program. For example: the elephant. But if Fencer is able to program it, why not use many pieces if there are people are interested in. A second problem is, the number of different figures you need. In the book (written in Dutch!) there are very nice figures and they are available, but not immediately all at once. It should take some time to solve this problem. The creator thinks that it is better to use his figures because these are balanced.
