Nah Kof13 isn't the best fighter out. If anything P4 is in my opinion. Like if I even had to list the best fighters out it would be
P4 - ok game execution based, easy to get into, actually pretty balanced as far as characters go
SSF4 AE 2012- Obvious top tier characters, Srk is way too good due to Fadc, easy to get into fundamental based game
KOF13- Obvious top tier characters, team synergy necessary, execution based game, touch of death combos
Tekken Tag 2- Damage is a bit ridiculous, tag assualts greatly extend already damaging combos, stance characters can set-up invisible mix-ups on tag ins, fundamental/gimmick based game,
MK9- obvious top tier characters, questionable balance, glitchy, fundamental/gimmick based game, heavy mix-up, touch of death combos, requires intermediate knowledge of each the characters gameplan to play efficiently
UMvC3-
Blazblu Continuum Shift Extend- Obvious top tiers, touch of death combos, questionable balance, damage is uneven for half the cast.
Skull Girls- Only three real playable characters, unbalanced,
that's just my feelings though
