I hope Miyamoto stays away from the story development of the next Paper Mario game. Him interfering with Sticker Star's story development was a big mistake that really disappointed millions. Miyamoto acts like Square sometimes; he doesn't like it when people expand the Mario lore, I don't know why but he just does. When Rare expanded the DK lore, he got really pissed off about it and hated the DK Country series. I'd love to see the X-Nauts return because Lord Crump and a few of them are still alive.
Legendary Spirit Tamer, I get what you're saying. I respect what Miyamoto's done for all of the Mario series, but he really screwed up big time with the Paper Mario series. Sticker Star was going to originally be Paper Mario 3D, and it was looking absolutely fantastic; until we saw more gameplay of Sticker Star, it looked awful. I got the game and thought it was an okay game, but as a Paper Mario game, it was awful. We got Color Splash and it looked like it absolutely played the same as Sticker Star, and many weren't happy about it. If you look at the sales, Sticker Star has 2 million, but we all learned from that game to not buy another Paper Mario game unless it was made like one of the first three games. Color Splash's total sales today is around 160,000... that's awful, and it's clear that the Paper Mario fanbase was really pissed off and didn't want to buy it.
Miyamoto also missed an opportunity with a better crossover involving Paper Jam. I got Paper Jam and loved it, I think it's much better than Dream Team, but he really missed a big opportunity with that game. The fact that he used Sticker Star characters was just... ugh, awful. Instead of having Bowser as the main villain again for the 34th time, they could've made a team up of Fawful and Dimentio. They only used casual Mario characters as bosses and characters, they didn't use anyone from Paper Mario 64, TTYD, or Super Paper Mario. They had plans for making Paper Luigi playable, but instead they cut him from being playable and made him as a complete joke, and they consider him as a "We don't talk about him" type of character; they could've made him Mr. L. If we had a huge crossover with Mario & Luigi + All the Paper Mario characters, we could've seen so many team ups like Popple and Mr. L; Fawful and Dimentio; Lord Crump and Midbus; etc. I know Fawful and Dimentio are dead, but I don't think Nintendo and AlphaDream care. We saw Fawful poof from existence in Superstar Saga, but he came back in Partners in Time as a bean merchant in the sewers. Fawful and Dimentio would've been the main villains and the both of them could've had a plan to try and betray each other. And when I mean a bunch of team ups, I mean that they're all affiliated with their own crew; no, the other team ups are NOT affiliated with Fawful and Dimentio, but most of the time it's Mario, Luigi, and Paper Luigi fighting them. Also, I would've made Bowser be part of the team, just like how he was in Super Mario RPG. Most of his moves would involve his attacks from Bowser's Inside Story but his special attacks will be his own moves this time (his attacks will be brand new), and it won't involve his minions like in Bowser's Inside Story because all his minions are brainwashed and work for Fawful and Dimentio now. I'm just so tired of Bowser being seen as a villain, because the dude clearly has a heart and does care about others, so I would've made him part of the team. And if we can't use Fawful and Dimentio, we could always use brand new villains.
I hope they make a good Paper Mario game like the first three again.
