Picked the game up last Friday. Took all the advice in this thread (THANK YOU) and added it to some Youtube videos I've been watching in the background at work.Had about 12 hours on the clock and nothing but losses in casual online mode.
My best friend (who has played fighting games his whole life and love SF) and I had our first chance to play online together tonight.
As expected, he utterly destroyed me. Again and again. BUT(!), he did comment that I was demonstrating smart plays so early on. He complimented my strong blocks and the fact I was rarely giving him a chance to anti-air with my jumps. I did beat him in just a few rounds, and he said I was doing a great job of keeping up the pressure. At the very, very least... I'm on the right track, and that I shouldn't be so hard on myself.
I definitely have the bug to find more time this weekend to get some more practice in. Non-stop, I could instantly realize what I was doing "wrong." It's fun to start to tell yourself "no, don't do THAT, instead do THIS."
