You guys are wrong. The skepticism and distaste only concerned the idea of a Mario and Rabbids crossover developed by Ubisoft, but all that was washed away by the first presentation of the actual game at E3 2017. The game's August 2017 launch didn't face any kind of uphill battle anymore, because the product itself had already convinced people.
Yeah, actually I remember my feelings back then. there were rumours of a Mario and Rabbids crossover before and I was kinda not too much into it. Then came the presentation and watching this my feelings about the game took a 180. They did indeed a good job convincing me that the game was worthwile.
