Sorry TV, but you're not showing any strong arguments in your favor. Nobody, including me, has seen the connection you're making and everyone has shown better counter-arguments. It just sounds like you haven't played XIII at all or at least long enough to get a feel for it. Your basis of a good KoF game shows the same if not worse flaws than XIII, since early on XI people discovered exploits and huge combos that with the scaling make it needlessly longer, like the Vanessa infinite or the serious balance issue which made most players use the Gato, Kula, Oswald team. While XIII was better balanced allowing all characters to have a fair shot and equally damaging combos.
If you just don't like the direction XIII took, be it the art-style or gameplay-wise (Such as disliking the HD mode bar) you should just say so instead of trying to come up with a "clever" excuse for disliking the game, because so far it's been far from convincing, not to mention comparing the combos with BB is just way too far-fetched.
The way I see either you need to give the game a 2nd chance or just drop this discussion, you're only making yourself look bad.
