I played today for about 5 hours ranked, 4 hours practice mode and it was fun but the netcode is for sure not as good as MK11 or Tekken7. And this is the start time, where lots of people play. Will be interesting to see in 1 month. This game not showing Wi-Fi or a ping ingame is also very "old-school", I really wonder why the wheel always has to be invented new. Good features should be standard, imo.
(Is rollback a hidden secret in the "developer" scene? Can Sony not help them out? ...)
The game also works "decent" because this game has the biggest buffer in all fighting games. Fastest universal moves are 11/12frame with the jab (throw 10f). It helps for landing your combos and this makes most people think, it's a great netcode because they don't drop combos but for example reacting to stuff is way harder, like blocking or whiff punish etc.
It actually makes me sad this game does not offer rollback and a Wi-Fi feature in 2021.
(And so many new console kids use Wi-Fi because they don't know better ... It's really not meant to be used for fast games ...)
I will for sure keep playing the game, it has so much stuff to learn and I like that. Options, something I miss a little in MK11 but for sure not in Tekken7.
