Everfree Tales

If you have any ideas for arenas please let me know and they might appear

Oooh, where to start...

A TRON-like world inside a computer program
Underwater
SPAAAAAAAAAAAAAAAAAAAAAAAAACE
Inside somepony's body- or an even better twist, as Futurama-style tinybots inside THEIR OWN body
Inside a giant clock = http://www.youtube.com/watch?v=1y-epxoVun8
At an evil circus
miniature ponies in a GIANT world
Giant ponies in a miniature world
ponies as pieces on a Chessboard
A world where gravity rotates differently for each pony- like, the inside of a tube that spins in different directions for each pony
A world where the lighting is monochrome - http://www.youtube.com/watch?v=bmkxsQnNujI

I think that's enough out of me for now.

Oh lets see.
A arena where gravity is inverted
Where it's a tall tower and it's filling with boiling water
Who knows where with giant floating rocks/gears
A Factory style assembly line with shield to prevent ponies from jumping off
A grid with GIANT gears rolling back and forth along the lines.
Underneath a giant steam ventilation system where parts of the arena will be blasted with superheated Steam at random intervals

Obligatory lava level?

I'm kind of amazed nobody has suggested "zombie apocalypse" as an arena idea...

Clllllasssic Style.

Just a plain stone arena with nothing, maybe windows for observers, but nothing really.
