Just going to chime in on Paper Mario Sticker Star. If you've ever played the other ones (Paper Mario, PMTTYD) and liked the RPG element to it, they COMPLETELY changed it up. There is no longer that RPG feel of leveling up or equipping different items. They completely revamped the battle system to account for the sticker mechanic. As someone who's played the original Paper Mario and Super Mario RPG, I was quite disappointed but, as a game itself, it is really good.
