Couple me with the group that thinks the OP has a useful idea, but his suggested implementation won’t really accomplish this goal.
For one thing, in certain SF matchups, the only way to counter certain normals is with a given character’s specials. It’s pretty difficult to practically compartmentalize the game like this and expect players to actually properly learn. If you want to teach them normals, that’s fine, but you have to do it in the context of the whole game. If you just purely isolate the normals, it actually won’t do much when they graduate to the next level, because all they were taught at the “easier” level was actually misleading. All you’re really doing is wasting their time and, at the same time, starting them on some bad habits!
The game also doesn’t have the same breakdown as music games. If two beginners were to play your so-called “expert mode” in SF (that is, the game we’re currently playing in SF4), they’d do just fine, because the finer points of the game are hidden from them and they still just spam buttons. If you were to throw a beginner on expert level in a music game, they’d die instantly because they are required to know everything about the game to succeed.
The proper approach, as others have said, is a carefully narrated sequence of video and interactive tutorials in-game, which teach people about the finer aspects of SF and why their strategy of spamming shoryukens and jumping all day is not going to win. These tutorials will be optional (just like your proposed modes), and will go a lot further towards improving a scrubby player than simply artificially limiting their toolset (while normals are important, some characters are pretty garbage without their specials… what are you teaching them when they pick said character?). They can learn the game in pieces using the tutorials, but this type of segmentation (basics, intermediate techniques, advanced combos) is a much better way to break the game up than by normals, specials, supers, ultras.
Also, it sucks to think about it this way, but while we’re being so pragmatic, such a mode would take a loooong time for Capcom to develop, and would have to take priority over other aspects of the game that, frankly, are much more important. This type of mode is really just a pipe dream for that reason. :sad: However, fortunately with the advent of Youtube, the fans can create these types of videos themselves! I’ve always been interested in getting involved with a project like this, but I have no real video editing experience. And flashy video editing is mandatory in a project like this.
