Zygs are the main one's also i find that refs are far more stricter on Beta. mate aint got retail still and plaing up his the other day i had 4 players sent off, on retail i swear it would've been 2 yellows and a red, no more!
why are you asking anyway solid?? have you got the beta and thinking about Retail? if you haven't i'd just go for the retail, beta's not worth buying now!
