ECTS has been replaced by the Games Convention in Leipzig, which is far cheaper than London. I remember going to ECTS in 2003, London was bloody expensive. While it wasn't as big as the previous years (they moved to Earl's Court for the last years), there were people like Kojima and Kobayashi present (I got to see Dino Crisis 3 behind closed doors ;p). I think 2004 didn't have anyone of a certain importance anymore. It also had to compete with GameStars or something. Both are gone now.
Yep few of use went together to the 2004 show. Was pretty pants really. I dint bother to spend my cash going to gamestars.
