I hate BlazBlue. I really do. I only play it because it has a similar play style to Guilty Gear, and its online. If it weren't for those things, I would have never touched it. But recently I have been playing only Guilty Gear. Where I live, no one plays, so I am stuck playing the computer over and over, but that is still more fun that BlazBlue any day.
I like to think I am part of the hardcore crowd when it comes to fighting games, and thinking about it now, I hope they hold off making a new Guilty Gear. If they make one right now, with such a high casual player base, they will have to make it simple like BlazBlue to get the people interested. Look at Street Fighter 4 for example. They went back to Street Fighter 2, made it 3D, and added some more mechanics. 3rd Strike was deep, and it scared people off, just like Guilty Gear does. If/when the casual fighter craze wares off, then they could make the game for the hardcore crowd again, and make it just as deep, if not deeper, than the current Guilty Gears.
I mean, shit, they could even make a fun Isuka
