So what's everybody's least favourite/most favourite stage?
Most Favourite:
-The blank training stage (great for straight up 1v1)
-Paris
-Hades
Least Favourite:
-Probably Black Rock stadium. Way too much going on, zooms out too much, and is overall too dark.
Favorite Stages:
INVASION - So much win on this stage. The music, both parts of the stage are great, the Mash Up is awesome, it's just a lot of fun.
San Fransico - Fairly straight forward stage layout, but the music and mash up and hazards are excellent.
Columbia - The music here is sooooo excellent. The the platform in the middle with two stair cases come off it seems like such a simple thing but it cleverly makes the map a lot more challenging at the center.
Franzea - I just love the look of it, and the way it constantly evolves it awesome. Also pockets get created and some interesting things can happen.
Least Favorite
Alden's Tower - The climbing part is fine but it makes it hard for characters like Toro that have to work for their meter to get meter. Music is excellent in the beginning.
Black Rock Stadium - for all the reasons you stated
Metropolis - It isn't bad per say but it has too much going on and the stage hazards are kind of annoying, which can be either a good or bad thing depending on how you look at it. Music isn't that memorable either.
