A lot of people will disagree, but I loved Star Fox Adventures. It was easily my favorite Star Fox game.
3D Rayman games, the only one I played was Rayman 2, so that's all I can go off of.
BIONICLE, the game to the movie was a bit janky, but so much fun!
Pokémon Rumble: I remember only liking the first one (didn't play the second), and really disliking Rumble U. There's a mobile game now apparently, but...no thanks.
A very obscure one: Onslaught, from the Wii Shop. A first person sci-fi shooter with Wii motion controls, playing on an alien planet with giant bug creatures. Quite reminiscent of Helldivers or Starship Troopers.
Asura's Wrath: I think a remake would be nice, not sure if there's much space for a sequel, the ending fit quite nicely.
Xenoblade Chronicles X: I'm gonna count this as its own franchise separate from the other Xenoblade games, and a remaster, remake or sequel would be amazing.
Bonus: Borderlands 2 had a good setup for a sequel, an incredible villain and such great characters. I'd love to see where they'd take their stories, like Maya & Krieg. Should be about time for Borderlands 3, I'm sure it'd be great! (FUCK WHYYYYY)
