I got 3D Land right for Christmas that year (at the time, I was 13) and was pretty much instantly disappointed by it. Theoretically, it should be my favourite Mario game ever, because it's closer to the 2D ones (that I did grow up with the GBA ports of), but it's just so fucking BORING and EASY and SLOW. Mario moves like a geriatric tortoise through levels designed by people who clearly just wanted to go on lunch, and – especially these days – completing them all just feels like filling out a government form. If you told me the game was a reskinned licensed platformer based on a Disney movie, I'd believe you.I'm assuming this game is decently popular now because today's 20 year olds grew up with it right?
I really hate how gimped all the power-ups were, too – I could not believe they removed the flight ability from the Tanooki suit! What the F were they on!? That was the whole point of the suit! Nobody cared about the buggering tail whip! Even the little blue shell boomerang power-up was just the most boring thing in existence – it's exactly the same as the fireball, the projectile just doesn't bounce off the ground. It was worse than the one in Super Mario Advance 4 on the GBA – how is that possible!?
My view on 3D World is essentially the same, but I honestly think I liked it even less because of all the collect-a-thon bullshit they make you do. (I hate that in platformers!) I played the game exactly as intended many times, with four friends/siblings all making our way through the game together. During every single session, we'd beat one level, inevitably miss some green star or key or something, someone would say "Want to go back and play that one again?", we'd all groan, and play Nintendo Land instead (which, to this day, is still my favourite game on the console by a long shot).
THAT BEING SAID, not that I've played it, I do think Bowser's Fury looks very cool and I'd love to try it out one day. They should make a whole big-budget Mario game like that, with a strong balance of levels that are both open and directed, and that just lets you fucking use a variety of interesting power-ups again. GET IT TOGETHER, NINTENDO!!!!!
Also, speaking of the 3DS, here's a bloody hot take for everyone: As someone who got the console at launch and was heavily involved in the culture surrounding it, I thought the first year was pretty atrocious. The only games anyone was playing was Super Street Fighter IV (port of a then-three-year-old game) and some Tom Clancy tactics game. Before SM3DL, I personally had only Rayman 3D (a port of a then-thirteen-year-old game) and a somewhat-interesting Tintin movie tie-in that played a bit like the sidescrolling Prince of Persias.
The games that people were hyped for that year included Ocarina of Time 3D (a port of a then-thirteen-year-old game) and Star Fox 64 3D (a port of a then-fourteen-year-old game). They didn't even let you use the eShop until, like, 4 months in! I actually felt really disappointed in the console at first, and spent most of that initial year just playing DS games or the free GBA games they gave you after halving the unit's price. Though it did eventually get some interesting free downloads like Nintendo Video, it wasn't until games like Kid Icarus Uprising and Fire Emblem Awakening came out that I finally felt satisfied with owning one. (And, of course, at the end of the console's life, I loved it.)

Oh, and one more thing...
This is such an embarrassing mindset and doesn't even approach being tethered to reality. Just hope you figure it out one day, but that seems highly unlikely.
