I love the SNK games and this is probably the hardest I've had to dig up ref for anything, what a chore, wow. At first I was thinking Samuria Shodown, then I started hunting around and there wasn't much I could find of the stages that I loved so much when I would play it, SOOoo... I went with another favorite The Last Bade.
Here are my options:
1) The Last Blade: Fort Stage
The day before the battle, nicely lined up cannons, intact tower, maybe even a fruit or fish cart where the dogs are... and of course some happy little clouds in the distance.
2) The Last Blade: Graveyard Stage
This would be converted to a summer day time scene. Tree in full bloom, green grass, and hut/temple not trashed but in good shape.
3) The Last Blade: Yuki-Machi's Stage
I would earthquake the hell out of this... I know I know I'm horrible but screw ya and your Political Correctness.
3) The Last Blade: Zantetsu's Stage (Picking this one, yes that #3
Not sure what I would do to this one yet, maybe transform it into a sunken ship... dunno yet... but I really like it.
4) The Last Blade: Village Stage
Winterize it, probably add a village off in the distance or some other kind of focal point.
