As you know, Sonic has tried most things over the years, in addition to his successful platforming career, we have also seen him drive karts, fight, play tennis, play sports with Mario and even a little role-playing.
But... Far from everything has been successful. One of the most overlooked chapters in Sonic's long history is undoubtedly Sonic Shuffle, Sega's attempt to challenge Mario Party, which was released for the Dreamcast in 2000. Unfortunately, the game received a rather cool reception when it started, and it didn't reach Mario's levels - but the basic idea was still there and there are actually good reasons to believe that it could work significantly better today.
The most obvious is that Nintendo releases its Mario Party so rarely so there are big gaps where people are screaming for minigame enjoyment. Party games with board game elements, mini-games and classic Sonic characters are really a perfect combination. Sonic Shuffle had all that and charming presentation as well as some fun ideas. The problem then was Sega's stress with the poorly selling Dreamcast and the threat of having to leave the hardware segment, which meant that it never really got the love it needed.
But this is where today's gaming climate opens the door. Sega today has significantly more experience in managing Sonic in different genres, and is today a rock-rich and competent developer and publisher. In addition, there are the digital marketplaces that make it much easier to release niche titles that still reach a wide audience. Playstation and Xbox gamers would probably throw themselves into a good party game with Sonic and the gang. In addition, thanks to the arcades, Sega has enormous expertise when it comes to creating good and intuitive gameplay loops... and it also seems that they are eager to take on Nintendo again.
Then complement that with good online support (Nintendo Achilles' heel in virtually all games), and we could have a challenger to social party games like Among Us and Fall Guys. Sonic Shuffle, with its unique card-based board game mechanics, could easily stand out from the crowd and give Sega a long-awaited expansion of Sonic's universe with a title that suits just about everyone.
In short, it's time for Sega to dust off Sonic Shuffle and give it another chance. The fact that it flopped was never because the idea was bad – but because the game didn't measure up. With the right skills behind the controls, redress is deserved.

How keen would you be for a Mario Party-inspired Sonic game?
