In my eyes, this is the best remake of a Pokemon game I have seen, it's mostly because it just adds so much fun stuff like party XP and Mega evolution and new forms to the Pokemon from generation 3, all in all a better package.
It has all of the strength and all of the weaknesses of the original game but now there's just more good stuff. So if you're not a fan of generation 3 this will not change anything.
A lot of fun double battle, there are a lot of Pokemon from this generation that I really enjoy using, and now they have mega form so even more useful.
The ocean is a boring place with only some Pokemon trainers here and there, and way too much repeated Pokemon so it's not fun to explore.
It's one of my favorite soundtracks in the series. The game has a good pacing to it and doesn't feel too long, There is a good variety to the Pokemon so it's fun to Nuzlocke with.
The redesign of the character art looks amazing. I really think it looks better and give the game more character and Style.
Just a very good Pokémon game. Would recommend.
