I gotta say that Color Splash, graphics-wise, looks phenomonial, and I can't wait to look at it when I get the game.
As I said with Sticker Star, I despise the game for the fact that it holds nothing in comparison to the other Paper Mario games, but it is still a decent, playable game as a Mario platformer. It's sad that the Paper Mario series has gone in this direction, and I do hope that the backlash from this game's announcement will help them at least add more stuff like in the previous installments rather than just continue to stick the name "Paper Mario" without doing anything worth earning that title.
I do think that the paint is an improvement from the stickers, though they really need to return the experience if they actually want people to invest time in the game because I seriously might just skip half the enemies since I found that to be the biggest waste of time in Sticker Star. When gameplay becomes a sidequest, that's when things need to be fixed.
I found it quite enjoyable how on YouTube, when a game is being played/talked about, it says it in the description below, and on the trialer for this, it listed it as "Paper Mario: Sticker Star". Obviously YouTube doesn't even see it differently. :P
