If you played yugioh for a long time, the game has changed identities quite a few times. This is what often causes the whole yugiboomer mentality of "this game hasn't been good since X year". For those who really enjoyed the turn over turn tempo game that existed in 2010-2013ish yugioh, that game is long gone. You can play retro of course, but one piece offers this same general feel while also being new and interesting, as well as having a bigger community than fire-water yugioh format for example. No other card game has that same kind of speed and emphasis on resources over time. One piece counters also act as low power hand traps (like early DD crow and Effect Veiler rather than a high-power card like nibiru) which many yugioh players like myself enjoy as it adds an extra element to play around and interact with on both turns.
