I had a lot of fun with the tools it gives you such as the beforementioned Skill Swapping. I did not play World, so I can't say what is evolution and what isn't, but the endgame monster (the big big big boss, not the final monster in the string of post-game releases) was a fun little spectacle. They don't do Rampages at all, which while I found them charming I thought them unnecessary and others disliked them. They drop the Japanese aesthetic, which is a little unfortunate, but the hub is good and continuous. The new maps are cool, lots of exploration potential.
