Hello, First of all, I have no idea if this is the right place for such post but one idea has been bothering me for years.
Why didn't Ubisoft make a Rayman kart racer game yet? You know, like Mario Kart? I loved Rayman M/Arena as a kid and I'm a big fan of kart racers and I cannot really think of a better franchise for that genre than Rayman.
It could include characters from all games, including skins (like Legends does) and obviously the drifting system.
I doubt that it will ever happen but there is a micro glimmer of hope that someone sees this and thinks "this guy actually has a point".
There's not many games of that genre but they are highly appreciated. Just look how much people love Activision's Crash Team Racing (yeah I know it's a remake but still)
