Yet every character in CvS2 has a chance at winning because of the groove system. 6 grooves do more to compensate for one-sided matches than 3 SAs per character, particularly with P, K, and sometimes S (all of which can counter just about everything, and are heavily dependant on your judgement and execution) as last resorts.
And “freak” players are a lot more significant than just being unique and impressing everybody. They don’t display how good certain characters CAN be. Character attributes are obviously well-built into the game, so they show how good they’ve always been. You might think they’re exceptionally gifted, but you know what? We’re all capable of pushing our limits. Effort affords you to gradually gain a better understanding of a game and encode new shit into your brain. If these players can be manipulative with a specialized character/groove combination and prove that it works, so can you. Furthermore, if these players had a bigger following, I’m sure both games would more or less be looked at the same way. They’re not though because of the apparent lack of interest. In spite of Doc B almost kicking Daigo’s ass, not one person in Japan or in most of the US to this day will pick up S-Groove. It just doesn’t match everyone’s style. It’s ironic, really, because mind games are a big part of CvS2, and mind games pretty much describe the groove best. It can’t be that no one plays it because it sucks.
There may be more variety the bigger the crowd is in question for 3S, but you don’t have a lot to choose from, and it’s just easier to get accustomed to the characters because the gameplay isn’t that deep in terms of available system options. That hardly says anything about balance. In fact, that’s why 3S’s so much easier to tier. CvS2’s tiers are always in dispute, enough to the point where even the top 5 are each found to be countered or beaten by an increasing number of people.
