Street Fighter IV
The gameplay designer on SF2 HD Remix has a few interesting comments about the design mechanics of Street Fighter 4 (in which he had no involvement).
I haven’t played too much of the game, but most of the comments I agree with. I do however think it is “casual friendly” in that the game is very lax about the direction motions needed to do basic moves, to the point where its easy to trigger a DP move instead of QCF, and vice versa.
In this sense, it is casual friendly since the basic specials can be pulled off with relative ease. Certainly, there is a lot of “depth” in the moves, which Sirlin regards as unnecessarily complicated moves.
