Beat the game on Hardest for the first time last night with my main, Sagat.
Wow. Practice really makes a difference. 50 hours of gameplay ago, I hadn't played SF in 10 years. I get SF4 and the first time I play it, I actually LOSE on Easiest - I was terrible! Practice really helps, along with this board and my SF-crazy friends. SO THANK YOU GAFFERS! Some of your posts really help, and figuring out combos and when to unleash ultras is really important, along with good timing and patience.
Seemed to figure out what works for me and what doesn't (need to stay calm, plan, and don't jump in or get all mad!!), and seem to be getting it now. Got a online win percentage of 69% with 300 matches under my belt, which I think it pretty good for a n00b.
Still need to work on challenges. Time Attack Lvl 11 is making me its bitch and I am stuck on lvl 20 on Survival.
