How Long Have I Been Asleep?
We will most likely continue to have three Metroid stages in Smash 4. One from Metroid: Other M, one from Prime (Tallon IV or Skytown please) and our good ol' Super Metroid/Metroid cave/acid stage.Some suggestions Scooby (or shoud I just say ideas from my own stage lists that I'm not done yet, since I'm lazy/I'm actually finding the music for them all)
For Metroid you should add in Skytown, and I'd also say remove Chozo Ruins and replace it with something from the non-Prime series, though that could just be my own want of Skytown. Still I think that's slightly more justified than Chozo Ruins, since that was from Prime 1, which already has a stage, in comparison to Prime 3 which wasn't recognized in Brawl. In addition I'd also add in Sauria from Star Fox as their second stage.
As for Fire Emblem, I'd say there are two ideas that I've been thinking of adding to my list. First off is the Tower at Medon from FESD (maybe it was in the older games as well?) In game, its really like a giant elevated platform swarming wtih wyvern riders, and I think it'd make a good stage for Brawl. As for Ike's stage, I'd say it should be the final level of Radient Dawn, inside the Tower of Guidence. What type of level that'd be though I havn't come to a conclusion about, though that's just my own problem, so I don't know if you need a explination of what the level should be.
M: OM stage
Tallon IV
Norfair (SSBB) (transfer the Brinstar Depths music over to the stage)
Also, PLEEEEEEEEASEEE Sakurai, give us a Saturn Valley stage with ACTUAL music from Earthbound!
