I mentioned the Pyscho Drive since someone else mentioned the internet, two forms of technology.
Goutetsu could Hadouken, and I’m sure many other fighters of that time and before could manipulate ki. What makes the difference is the technology. I really don’t think Capcom thinks "SFA is in the 80’s ummm SF3 was in 1999, when should SF4 be set?"
Oh and the Tim remark, was a Home Improvement joke.
