I see what you mean but that seems like a hell of a stretch IMO, games with moves tied to having low life existed before SF4 and they have existed independent of focus attacks.It's been advertised as such ever since the day it was revealed and I don't really care if you disagree.
If I struggled to the end of my determination, to the end of my way of life with my followers, if the result is ruin, then this ruin is inevitable. Grieve. Shed tears. But you cannot regret.
