thats just cuz i know how to play smash though, and when watching videos I understand what I'm seeing. and also because characters in smash are way more similar to each other than characters in other games
i'm hesitant to think a person could be tournament ready in two weeks if they've never picked up a fighter. Unless they legit find a 50 page guide on "how to play fighters" on the internet or something and also are some kind of genius. there's so many things that you just 'know' already whenever a new game comes out just because you've been playing fighting games for so long. you know what you're looking for. mid screen combos, corner combos, otgs, blockstrings, overheads, reversals, counter hits, anti-airs, mixups, throw set ups, super armor,, karas, cancels, links, hit confirms, option selects.
i can't imagine that a person who has literally never played a fighting game would even know where to begin
