people gotta stop bringing up brawlhalla when saying a F2P fighter can work.
look at brawlhalla look at it, thats what a f2p will look like, look at how many characters are just reskins, thats how characters will be added. To people honestly want that? Ryu isn't even a character in that game just a reskin, would you guys really want a SF7 F2P where they drop 5 Ryu skins that are just Dan, Ken, Akuma, Gouken, and Sean.
I think people just look at its success and don't see what kind of game it is basically a fortnite fighter where every character is just a skin and their movesets don't matter (I do know there are multiple characters and its not the same moveset for everyone)
Long story short, your never getting a SF7, Tekken 9, MK2, etc quality game but F2P, if you do your gonna complain that everything is to expensive, and if you get a brawlhalla tier game you will complain as well. Killer instinct, granblue, and to a lesser extent DOA did it right free to start, the player can mess around with the game see if they like it and buy it if they want.
