One Piece Unlimited World Red.
The Wii games were all about collection materials and exploring the nook and crannies of the levels. Like an Atelier game with real time combat and 9 playable characters. All of the crafting was geared towards unlocking new moves and areas or getting a more resistant rod for the fishing minigame, which was useful to get rare fish and cook HP boosting recipes with Sanji or revival items with Chopper.
You trained each move by using it and each character had different traits to them (long range/ traps for usopp and Robin, electricity for Nami, cutting bamboo with Zoro, running over water with Brook...) so using different characters to beat up enemies and exploring always felt rewarding.
So you could expend hours in those levels training, exploring, fishing and gathering materials, and the levels had a lot of verticality as well. I know I did.
But UWR was a multiplayer-centric game. You no longer had to unlock or train moves, most of the maps were simpler with barely any collectibles and no reasons to revisit them. And the real time motion controlled fishing from the Wii was turned into a button mashing minigame that was harder if you played alone.
Just comparing these two maps from Unlimited Cruise 1 and UWR can give you an idea of how much they simplified the whole thing. If I remember correctly all those stars were roadblocks where you needed to bring an specific number of items to open up the path, including secret areas and bosses.
But for UWR, instead of playing each level for hours to unlock hidden areas and bosses you'd just play the level to reach the boss and move on to the next one. I ended up expending more time in the side modes like the colloseum or the tavern missions, because the main game felt very lacking by comparison.
And then World Seeker removed all the other characters in the crew and the 90% of the crafting altogether and set the game in a single, big and open location. All the crewmates stay on the ship and barely do anything.
You had some (confusing) exploration on the closed areas like the mine and prisons, but for the most part you're just launching yourself around the map with nothing much to do other than picking up glowing spots and hoping they're useful later.
