Only noticed this thread today, loving the idea. Finally I'll actually check out all these classic games, instead of gravitating towards my favorites (first game I booted on SNES Classic was Yoshi's Island, instead of nearly dozen other classics that are featured I never finished before).
So I started Mario World today, curious how far I'll get. I always had weird relationship with Mario World, it's obviously one of the classic Marios but I never really loved it that much, something about the physics engine always felt weird. Surprisingly, the 'main campaign' was shorter than I expected and I managed to save the princess within one day, so hooray! #euro #morton . I hope this one without a photo is acceptable, I'll make one as soon as I finish 100%.
That said, this will be the first time I'm going for 100% in Mario World, which is kind of exciting in on itself. I never really pushed towards 100% in 2D Marios, did some bonus levels here and there (especially in NSMB subseries), but usually didn't push to full completionist runs like I did with 3D Mario games. I'll make sure to come back to the thread once I experience the supposed horror of Outrageous and the legendary Tubular.
I don't know what it is, playing it without save states, pushing towards completion, playing it for the first time with the proper intended controller (it's so good, really makes a ton of difference!), or maybe even the positive attitude exhibited by everyone in this thread, but I've never enjoyed Mario World as much as I did today.
I do fear how my attempts at executing glitches will go though, hah. Never played around much with glitches beyond Pokemon series (Mew in Gen 1, various cloning, surf glitch in Gen 4). I am very intent on succeeding though!
