Thanks for the help with the match-up guys, in all honesty there is so many questions I have to ask, i don't think that a Bang match-up thread is pointless there maybe more things lambda can do against him that were just not thinking about.
As I live in the UK I had to pre-order a copy so I should give it a spin next week sometime hopefully. as I remember the match-up is a 3.5-6.5 in Bangs favour but thats hardly terrible when other games have 8-2 lol. Anyways i'll save it for the Match-up thread.
As for practicing on Cpu i don't think that theres a problem with it for beginners however I don't see it doing much good for vetern players as the cpu will most likely play completely different to a human player, however to get to grips with the game and the characters then I guess it's helpful.
