UK Games Expo is not a place for games, but things that make your games look kick ass.
Battle Systems will be there, showing off their awesome card terrain system. After a number of successful Kickstarters they have a range of fantasy, scifi and modern terrain, perfect for a variety of games. I've had a chance to talk them in passing at the Beasts of War studio, but it will be good to catch up with them and see what is new.
4ground will be there too, with their excellent range of laser cut terrain, designed for different scales and genres. More recently of course their Fabled Realms terrain set is also a lead in for their upcoming wargame.
