Tekken 7, I have recently started and I really like the complexity of a 3d fighter. Major plus is that its a 1v1 competitive game, so all my losses are on me. I can't blame my teammates nor do i have to depend on them to not lose the game.
You need to lose your fear of losing as quickly as possible to enjoy fighting games. (Also you won’t lose as much as you think.)
Tekken in particular you really just need a couple of core strings and learn to block.
