What franchise has fallen to the wayside that you'd love to see come back with a reboot or new entry into the series or what genre would you like to see come back that just isn't popular anymore.
For game, I'm gonna start with a big one, Mega Man Legends. I'm sure there were those here that was upset at how unceremoniously MML3 was canceled, even before the prototype was to be released. That game alone was basically gonna sell me on the 3DS and because it didn't, I didn't get one for a while afterwards. I love that series and really want it to come back. Hell, I'd take an HD port of the first two games if I could get anything lol
For genre, the 3D Exploration Platformer. Your Super Mario 64, Banjo-Kazooie, Donkey Kong 64, Jak & Daxter, you don't see these kind of games anymore. It's all 2D platformers or stuff more like Ratchet & Clank that is still getting made, but I never considered them the same, just as I don't consider Jak 2 and 3 to be quite the same as the original. I want to see Nintendo have Mario be in a huge, beautiful, HD hub world full of stuff to explore where you then go into big cool worlds that you explore rather than the small linear levels that all basically just been copy and paste stuff of Super Mario 3. Thankfully I did fund one Kickstarter called "A Hat in Time" that is very much a game calling back to those glory days which I hope turns out well.
Look at the games nowadays. Super Mario, even 3D Mario, is mostly just the same linear overworld of Super Mario 3 and linear levels. Donkey Kong is only in the Donkey Kong Country form. Banjo-Kazooie's latest game was a build-a-cart racer with mild platforming to it. I'm kinda hoping that the new Sonic Boom game which is said to be a more open adventure game can do for filling that kind of gap in gaming especially since it has some Jak & Daxter vets on the team for it. I also just want to say, that while I point out the above games, they are in no way bad and are still good games, but I feel like there's missed opportunities here to revive a long lost genre I treasure dearly.
