Dude I'm so excited for you right now. It was such an amazing day when I found all of this the first time.
First of all MP1/2 and Dread have a multi world randomizer called Metroid Prime Randomizer. There's a discord, it's a cool community.
But more importantly there's something called Archipelago.gg, which is a multi world randomizer across MANY games. The few dozen on their site and maybe 120 other ones, of course including MP1 (and 2 is in alpha I think). My friends and I do a big one a few times a year and some smaller ones throughout. I really like it. It's so funny and confusing to think "my grappling beam is stuck in Pokemon but he needs surf which is past some Stardew checks but she doesn't have Summer yet which I think is in hollow Knight ..."
The list of non website games is on the discord server and there's MANY more. Highly recommend looking there
