I got Elder Sign for my christmas. Best present ever. It can be played 1 player as well but for that I just play the iPad version. As for Catan, I bought the expansion packs for my mate and they make an already great game even better. I do want Star Trek Catan, I think I saw it in Waterstones before xmas. It's payday tomorrow so.................. Also had a conversation with a guest at the hotel I work with. He said if you like Catan to look for something called Tikal. Haven't had a look yet but he seemed real excited about it.
