Tazumili Village (Mother 3)
This is a nice and peaceful village... and Mr.Saturns are floating all around! It is a large area which is perfect for big characters such as the Metal Gear. (I hate Nintendo's new localization for the village's name. During the N64 Disk Drive era, Mother 3, then a 64DD title, was going to be set in Tazmily Village).
Pokémon Stadium (Pokémon)
Most of the time, Pokémon trainers just battle where ever they see other Pokémon trainers. For tournament styled battles, however, a stadium is used. There is not alot to say about this stage. It is small but has enough open space for big characters to feel comfortable in.
Sector Y (Star Fox)
Sector Y is a location in the Star Fox games that contains a lot of asteroids... A LOT. In this stage, you don't only have your opponent to worry about, but these asteroids as well! Still... Its kind of cool how they explode into tiny bits...
Popstar (Kirby series)
Popstar is like the mother of Sector Y in respect that it came before the Sector Y stage. Like Sector Y, Popstar is in outer space. The difference is that Popstar does not have an asteroid shower. Instead, it seems King Dedede came around before you and left some Gordos. Originally, Wispy Woods was going to pop out from Popstar at random times and blow everyone away.
Players should be careful not to touch the Gordos. Their spikes are not for show!
