What do you want in the next Metal Slug game?

Yup, the different character styles is what pops to mind for everyone, i guess.
It really would give the game a whole new depth and longer gameplay value.
Would be nice to see different weapons stronger with different characters.
For instance, the rockedlauncher and enemy chaser would be a whole lot heavier and awesomelooking when Tarma plays with it compared to others.
And on the other hand Fio could have a souped up laserrifle that is more powerfull when she plays with it compared to the others.
And more of those type of trhings...characters that react differently to different type of the weapons.

Same could go for the slugs.
Marco would be awesome better in the submarine, while Eri is more powerfull to use in the airplane and helicopter, Fio would on the other hand be far superior in the animal slugs(camel,Elephant,etc)...and tarma could be better using those heavy armor slugs and the origina slug. ;D
