There will be haters in any debate. I'm stating why I think Akatsuki is crap. I'm not actively seeking its destruction. I think it's a waste of time. Just like me playing IaMP is a complete waste of time even though I have fun with it. Bad games can be fun(though I think IaMP is good even though I blow chunks at it). We all know this.
Your speech is makes complete sense, too. Good things, regardless about how little exposure the things have gotten, need support. I honestly think Akatsuki is not worthy of that kind of support. It's fun, but it's not good. Let's start with graphics. Akatsuki uses mid-res sprites with low frames of animation. The frames that are there are chunky and do not give a very good idea of fluid movement. In all honesty? Looks like a mid-res SNES game. Even Gundam Wing: Endless Duel has more style.
BBB? BBB uses nearest-neighbor scaling to zoom in and out of the battlefield like Last Blade and other Neo Geo games did back in the day. It is definitely not pretty. But what really matters is that it opens up gameplay possibilities by letting characters be at complete opposite sides of the arena. Along with that, the sprites are very fluidly animated like MB's sprites. Graphics aren't great, but they have good style. I believe this places it above Akatsuki graphically.
The music in both games rock, too. Both games have very few characters. The system, however, is what makes or breaks the fighting game in the end. Akatsuki's sytem is pretty simple (read: boring[opinion]) with a very small moveset, very few combos, and a parry system just like every other fighter out there. BBB's systems has much more to keep up with, which is more in tune to the majority of common fighting game player's interests. Gauges, stock management, k-k-k-krazy combos. Complex system makes people work harder for their status which feels much more rewarding. You may disagree with this, but I believe it's a very important cornerstone of interest in fighting games.
So if I'm shitting on Akatsuki, it's because I honest don't think it's a good game. I'm not here to create heightened drama. I'm here to support MB first, and post my opinion second. And my opinion is that Akatsuki fucking blows, and I think the community who actively supports it blows (read: is supporting a shallow, boring game that won't catch on no matter how much they support it[opinion]). They may have fun, and good for them! Doesn't change my opinion of the game.
