Quoted from FatPanda:I was thinking along these lines. Kinda leaning towards LM3 right now. They don't have precision platforming skills (yet) and not really looking for anything that requires too much puzzle solving. Have you played any/all of these? what are your thoughts? It should be something my wife and I could play too, but i'm not opposed to getting something just for the kids.
I personally own all of those and have played them all. However my oldest is 3yr old.....sooooo she can't really play them that well. usually she can get the first level or two, then it becomes too hard.
If they can play odyssey, and are into mario, the 3d mario world w/ bowsers fury has 1-4 player, is "easy" for a mario, but hard to 100%, and bowsers fury is coop (more like mario odyssey) and is a great mario sunshine mixed with 3d world. I'd probably recommend that game first. You get 2 games in one, I have this on wiiu and bought it again and am very much enjoying it on switch again, and my daughter loves to watch and try to play.
I also think yoshi's crafted world has more of a basic platformer that can be hard ish but you can enable an always able to fly button. Which is helpful for the younger kids. Demo is available.
Kirby star allies is nice as it takes LOTS of hits to kirby to "kill" him. Demo is available.
Toad treasure tracker is a slow paced puzzle game. I enjoy, not sure kids unless they are into puzzles
LM3 - sooo there are a few spots in this game that SUCK even for an adult to figure out. I had to use a guide on those to know what I was supposed to do or go, however the basic play is not toooo bad. Big puzzles are the boss fights. I don't know if I would put this at the top of the list unless they didn't like the above game/demos.
the new super mario bros is hard, it's a good update to the original mario games but is 1-4 player.
For sure get the demos and have them try those, otherwise I hands down, suggest the 3d mario game. Watch some gameplay and see if your kids would dig it.
