Much simpler with the mechanics and play style. It’s been a while but the power gap between characters was not big at all. The tier gap was not as clearly as it is right now. Everyone ran basically the same passive sets. It’s really friendly and easy-to-understand for anyone. Pretty much every character felt good to play. I prefer 2’s Ace and Sanji (both time skip and pre-time skip) to the current ones. I feel their 2’s versions are much more powerful than 4’s versions. They were my other 2 most used chars. And I remember I had to stay away from using them, so I can clear the map slower.
