I dunno, I think X and co. have plenty enough character depth to drive an anime. God knows there's a lot more than TDoS that's been left unsaid in the games.
I wouldn't say that Classic is lacking, more like it's already been done. We have RS, we have Upon A Star, we have Archie's comics, and there's tons more out there.
The source story being limited means nothing; if anything it creates an opportunity. Any decent game adaptation needs to stand on its own rather than remain strictly within the confines of the game story, or else it's just redundant. As an example, just look at Sonic SatAM. The games, in terms of storyline, offered jack squat other than the robot theme to the villain. The show took the games as an inspiration, and from there succeeded by its own merits.
Granted, Ruby Spears wasn't horrible. It could have been much worse (Captain N). It was a pretty good show for what it was and what little source material the people had to go on at the time; however, we don't live in the early 90's anymore. What they produced is understandable once you put it in the context of the era it was produced in, but such a thing won't fly anymore. We know what the source material is now.
The character design of the show was perfectly fine. Roll is the only real offender in terms of anyone not bearing a reasonable likeness to the source (by "reasonable", I mean within the same margins that the entirety of the fanbase accepts between Ariga and Rockman Online), and I'm sure getting her a new outfit could be easily arranged. Yeah, ProtoMan needs to stop working for Wily (that's a result of the show pre-dating Bass, and we all know it), and the general atmosphere could be a little less cheesy, but all of that is a pretty simple batch of adjustments.
Not that I believe anyone
would pick up RS, it's just too old. I'm just saying, if someone did, there's no reason it couldn't work.
