Your lack of Blazblue is disturbing....
Anyways, my top 3 favorite fighting games of all time are: Guilty Gear sereis, Blazblue series, Dissidia series. It's a three way tie I guess because I find them all equally awesome and worthy of praise.
All of them have incredible, fun, and deep fighting systems; just top notch gameplay overall. The aesthetics are great as well with awesome character design and vibrant visuals. They all hit the nail on the head when it came to the most important aspects of a fighting game that make them so appealing.
They don't commit the horrible sin of the "clone", every character is unique and no one plays alike. So much variety, and characters that fit every player niche.
They have deep and interesting combat systems. They fit the "easy to learn, hard to master" phrase quite nicely, and the complexity of the game never proves to be daunting despite how much that's going on.
And not to mention they have excellent and insinuative controls.
I never get tired of playing these three bad boys. I love other fighting games, but these guys sit at the very top of my list.
