Favorite All-Time Mario game?

What is your favorite Mario game of all time?

Mine is definitely Luigi's Mansion. It's the oldest Mario game I still have and the first Mario game I got on a physical copy (I could argue that Game & Watch Gallery 4 holds that distinction, but I consider that more a Game & Watch game than a Mario game). It's very fun, and I enjoy the spookiness to it. I've completed that game so many times, but I still come back to it again and again.
 
super mario world cause of all the memories i have with my snes and playing with friends/family/etc. or even just by myself and trying to find secrets and just progressing through the world.

it taught me a lot of things, like the words "dome", "valley", and "illusion"
i was still like 5 or younger probably when i played this game so i didnt know what they meant but then like when the word popped up in literature or something later on in school i just sorta remembered from the game and was like "oh ive seen that word before" (i guess it sounds kinda dumb but w/e)

and also made you use your brain to solve problems (games like smb3 back then were just linear most of the time, not saying it was a bad thing, but smw was more complex)
like, once again from 5 year old me perspective(i still remember me sitting there paused trying to think this out lol), the exit in choco-ghost house was pretty tricky, and you had to use perch block boos to help you stair up. i dunno but that was pretty complex for me back then playing the game, cause i literally thought the only way was to fly up there with a cape but it was hard or i kept losing the power up to the string of boos that would bounce along the walls.

ive also completed it many times and the replayability is pretty high for me from time to time
 
super paper mario

was the most enjoyable game with the second highest replay value, for me (first would be super mario galaxy, which is also second place in enjoyability for me.)
 
Super Mario 64, easily. There are so many ways to play the game which opens up for so my replayablilty. I don't think a single Mario game has given the player as much manoeuvrability as Super Mario 64 has, ever. I always enjoy finding new ways to obtain stars. Hell, even just moving around is fun. Everything in Super Mario 64 is just pure, distilled fun.
 
Nothing will ever beat Super Mario Sunshine in my eyes. That game was and still is so much fun that it's ridiculous. I think FLUDD was a great mechanic, all the worlds were so memorable and neat to travel around, the secret levels without FLUDD were so, soooo good, and the music was fantastic.
 
I used to say sunshine but I've been rather enjoying a lot of them lately.
 
Mario Kart 8, if they're not modded.

Hard to count Wii games thanks to homebrew, which makes Mario Kart Wii and New Super Mario Bros. Wii (Newer in this case) a totally different experience.
 
New Super Mario Bros. Wii if you factor in mods, especially Newer Super Mario Bros. Wii.

Without mods, probably Mario Party 6, but I hardly play Mario games without mods nowadays, so *shrugs*.
 
super mario galaxy
the levels are really fun and well designed, amazing soundtrack, and rosalina is an awesome character
those storybook feels
 
I like so many, especially the GameCube games only because of nostalgia, but I think I've finally settled on Paper Mario The Thousand Year Door. The unique atmosphere, characters, and dialogue were all great in my opinion. Glitzville and Excess Express were some of the most different levels, and we probably won't see any more like them again. And so be it, it makes TTYD greater than the others in comparison.
