probably most of the mk3 arenas because they added a lot of the mk2 backgrounds on deception.i would love to see the pit3 in 3d

i would like to see mk2s pit, mk3s portal, and a modified version of the quatan palace.

The Temple MK3, The Pit 3 MK3, The Portal UMK3, Khan's Arena if he's the boss MK2, and Jade's Desert UMK3

A lot of people wanted Khan's Arena,The Pit 3 ,The pit 2 and the Belltower, in Mk:D, so since everyones wants these Stages, then should be in the game!!!

it would be cool to have a multi arena or kinda like : From THE BANK to THE ROOF and from there the battle goes on on THE STREET and Then to THE SUBWAY something like that

I would like to see The Bank back. I would also like to see the Sanctuary from MK 3 and the House of Pekara somehow combined.

Others include the Subway, Quan Chi's Fortress, the Armory, and the Wooden Tower.

I'l like to see arenas from the Order and Chaos realms and the nether realm, conquest mode really fleshed out the worlds.

Like for the chaos realm, wouldn't be cool to have a Chaos realm Graveyard arena with floating coffins all around you that you can knock an opponent into and the coffin floats back a little.
Or the Water factory area could be truned into an arena.

In conquest mode, we where shown a Colliseum like area in the nether realm, I feel that area has alot of potential to become arena. It would really be cool if a the colliseum seats were filled with oni cheering on the match, and you can knock your your opponent into the crowd who will tear him to peices for a stage fatality.
