It's probably gonna be the Mario of the decade and then some. The 80s had 1 and 3 (sorry, fans of SMB2 but even if it's good [which I'm not arguing against] it wasn't the original and also didn't blow the doors off like 3), the 90s had SMW and 64, the 00s had the Galaxies, and this is the first one since Galaxy 2 to hit the ground running and dare anyone to review it negatively.
From what little I've seen (first two worlds only), this could be a new template for them to work with for easily 1 or 2 more main line Mario games before it even begins to seem redundant or lazy. After the safeness of the "New" series, it's excellent to see them really trying new ideas and executing as well as they have. No knock on the New SMB series either. It's very fun at times but still had a lot of room for where they could've appealed to 2D Mario fans but in a more original and captivating manner.
