Hi, I'm new in the world of speedrunning, I don't know very well if I have to collect the stars in a necessary path. I'm sorry for my awful english, here in spanish if someone can understand.

Se tienen que recoger un "Camino prefijado" de estrellas si o si? Es que soy nuevo en esto. Me refiero a: / I refer to: -Chain Chomp´s Gate star. -Whomp Fortress Shooting to the Cannon star

Etc... If someone can answer, thanks. Idk if I explained well

i think this will help you https://ukikipedia.net/wiki/RTA_Guide/16_Star in whomp fortress for example you dont need to do the cannon before the others, its just common to do this one, because its the "hardest" star

but... is it necessary to do some... like... Forced-ly? idk, my eng. sucks, also Idk how to express it in spanish.

The only requirements for 16 star are that you beat the game without using SBLJ. You aren't forced to do anything else. The only star that's required is the submarine star in dire dire docks. The other stars you see people get are just the fastest ones to get Mips to spawn. You can be as creative with the routing as you like, but the community knows which stars are the fastest. Hopefully that helps!
