Thurn & Taxis and the expansion

I got the new expansion for Thurn & Taxis and immediately we played a 2p session. Firstly I realised that I had played T&T wrongly for so long now. I have completely forgotten to reduce the points for houses not placed onto the board at the end of the game! Thanks to BGG I noticed it only today. anyway coming to the expansion, it is a new board with new cards. The only thing you need from the original game is the houses in the different colours. As someone posted on BGG, you don’t even need the original if you just get the expansion! Personally the expansion provides me with just that different feel and interest for someone who has got bored of the original but liked it a lot. So unless you really loved the original, played a lot, got bored, but would not mind playing the same game with a subtle shift, this expansion is not worth it.
