It's something like this...
G2-E 2000GP
G2-D 3000GP
G2-C 5000GP
G2-B 7,000GP
G2-A 10,000GP
Once in G2 you can play anyone from G2-A to E. Over 15,000GP takes you into G1. I have a mate on G1 who's a Sagat player, prob the best Sagat player I've played, I struggle to even get a round from him. As far as GS goes, don't think anyone has made it into that yet, maybe 50,000GP?
Not sure tbh, I won the final against a 14,000GP Ken player and it automatically gave me the option to upload so I did.
No never had this on the xbox, I played you afew times agesss ago on SF2HDR, but never on SF4. You whooped me on that

For some reason I struggle against good Guile players so it might be the same story on SF4 lol but yeah thats my PSN nick, add me on!
