Maybe 2D Mario sells better not because people find it better but because they simply never tried (and don't have interest) on 3D Mario?

2D Mario is ubiquitous, and has been selling a lot not only on NES and SNES, but also on handheld lines, I won't be surprised if that's the only Mario many people ever played

Wonder for me. As i've mentioned, im a sucker for 2D mario games as it was the one that started it all for me with the original SMB.

3D Mario is fun and all but there are a lot of fun 3D games I enjoyed more. But when it comes to 2D side scrolling platform, nobody does it better than Mario.

Super Mario Odyssey for me, and for a few reasons. One, it was treated as more of an event by Nintendo, with a phenomenal announce trailer. Two, it launched in the honeymoon phase of Switch, as opposed to its twilight. Three, and most importantly, the line of 3D Super Mario games simply has more street cred at this time than the line of 2D installments. Odyssey was the successor to Super Mario Galaxy 2 and Super Mario 3D World, where Wonder is the successor to New Super Mario Bros. U — a great, underrated game, if you ask me, but not close to the greatness of the Wii and WiiU 3D titles.

I think I was more excited for Odyssey, but that might have more to do with the tarnished reputation 2D Mario has gotten, in my opinion.

Before they started with the 'new' branding, basically every Mario was a completely new game and with a little more tweaking, they could all be their own franchise. The games kept innovating with every iteration (the 3D games kept doing this), spread across home consoles and handhelds, but then suddenly decided to become lazy and just rehash the same type of content. Probably because the sales numbers were so insanely high.

I do think Wonder will dethrone Tears of the Kingdom as the fastest selling exclusive and depending on how much time the switch has left, has a chance of getting to 50 million, simply due to the fact it is the first original 2D Mario in 17 years.

I'm going to do my best to not look at any more trailers for the game as the trailers for Odyssey showed pretty much every area and completely took out the surprise of playing it. It was a series of ''oh, yeh, I remember this from the trailer''.
