alt Hacker NewsThose may be difficult games but they don't have the twitchiness of a game like Super Mario Bros. They're on the order of 1/4s to 1/2s maneuvering (with great anticipation) whereas SMB is loaded with 1 frame tricks (1/60s). It's an order of magnitude difference.
Huh? 1 frame tricks are the top shelf of speedrunning moves, definitely breaking how the games are designed to be played by orders of magnitudes.
Speedrunners use 1 frame tricks in more modern games as well. It is considered extremely hard even amongst the already insane speedrunning community, no matter whether the game is SMB, Odyssey, or anything recent.
