I first started playing 3rd Strike after my brother in law showed me the Daigo parry moment. I was like... What? That's crazy! I downloaded GGPO and tried to do the same but it was very hard. I figured why not try to get better at the game. I only played for fun, but I was ass! I used Ken of course and didn't know how to play that well.
Almost a couple months later Street Fighter 4 came out. I asked my brother in law, "Should we get it?" He said, "Why not looks fun." First time I played it I chose Ken and I hated it. There was no parry or anything. I didn't understand that you had to anti-air, zone, space, ect. I tried to use Ryu instead since Daigo used him and I studied his Ryu. I didn't understand what he was doing but I just copied. What attracted me to Ryu was his fireballs and anti-air abilities. He was a very well-rounded character. I wanted just that - a standard character! I only went so far from studying Daigo.
Then I tried to learn Street Fighter 2 Super Turbo. That game taught me a lot about anti-air's, spacing and fundamentals in general. Everyone did so much damage in that game that you can't let a character jump-in. I used Ryu and it was very hard to play that game for me. It taught me appreciation for SF4.
