ok. Shoryuken.com is the first place to go for everything 3s. check the Wiki for accurate info, strats, and frama data.
look for people on SRK or possibly an arcade in your area to play against. ggpo is nothing in comparison. Every time i go to a 3s tourney I always get sent to losers like first game because my parry timing is off due to playing too much ggpo/2df
if you don't have humans around you to play, or don't plan on taking it seriously, then ggpo is the next best thing.
yea Ken is definitely the best starting character. hes very basic, relying on mixups, and super combos.
Akuma is definitely not overpowered in this game. hes good, but his health is so low and his damage output just doesn't make for him to be top tier. play against a good Yun/Chun and cry. Luckily for me I just tier whore it out and play Chun/Ken in tourney anyway lol. I main Ibuki though.
I gotta get on GGPO more tho. SF4 stole my soul but I can still hold it down in 3s if I play a bit.
