Since someone brought up BlazBlue, it's actually quite funny.
One of the biggest criticisms of Continuum Shift was that Litchi and Bang could combo you from coast to coast for massive damage for ten minutes for a massive chunk of your life, and even bursts didn't justify it. Getting hit by c. L in MvC3 will often kill you and there's absolutely nothing you can do about it. MvC3 gets a free pass, CS is called garbage.
CSII comes out and completely changes the way the game is played, with less emphasis on midscreen madness and more on cornering an opponent and putting the pressure on. It also went from 5 viable characters to everyone minus two being considered good, and with no dominant force reigning over the metagame. Arcade Edition completely destroyed the concept of balance and went from "anyone but Hakan could impress you" to " Super Twin Fighter IV: Fei Long Edition featuring The Rest." AE ruined a nearly perfect game and CSII vastly improved a bad one. AE gets hyped to hell and back while CSII is left in the dust.
