I'm generally unfamiliar with most GG games, but Accent Core was where it was at for me - boasting a phenomenal presentation and one of the most unorthodox, crazy casts in any fighter ever. Mechanically, the game is among the best - fast and hard-hitting without combos going on forever, an insane amount of mechanics that add complexity to the overall game, and best of all, it's fairly balanced. I don't know how this game compares to most other GG games, but many consider it among the best.
