hmm....my top 5 stages?
1) DOATECH HQ HK (DOA3.) A stage with 3 different tiers and areas. Awesome. If they bring it back I'd want them to add a 4th area in between street and lab on the ground floor.
2) the vegas strip (DOA4). Just a very pretty stage, and I liked the cars, kept people on their toes.
3) the cherry blossom stage, where you could go down into the canal (DOA4)
4) The snowy cliff where you could fall down to a frozen pond (DOA2U)
5) Lost World (DOA3). Not so much the DOA5 version, but i'll take what I can get.
So many old stages I love.
I think what they needed to do for Last Round was revamp the 5 stages with more stage breaks. Like for Mila's gym, make it so you could break out of the ring and fight throughout the gym, and even be knocked out the front or back doors, to fight in the "back alley" area behind the gym that you fall from the rooftop stage for, or a brand new area in the front, out on the street. Or better yet, remove the fence in the back alley area to combine the two, so its not just a box.
