As far as the NES game goes... the first two that come to my mind that (kinda) fit that description are Xexyz [https://www.youtube.com/watch?v=-A9l8Qgj_SU&nohtml5=False] and Layla [https://www.youtube.com/watch?v=Erl4ygNN50I].Bangief said:Okay folks, I have two I'd appreciate some help with! I'll give as much detail as I can.
1. NES game with two modes.
Mode 1: space shooter/sidescroller ala Tyrion, Gradius, etc.
Mode 2: spacesuit platformer with jetpack and gun (can't think of a similar game right now).
I remember the color scheme had a lot of blues and the space suit was orange (not sure about the ship).
I don't remember the story or objectives-- I think you would transition to the spacesuit mode periodically throughout the sidescrolling, then have to destroy something inside a room/building.
2. Fighting game on PC, probably played it in early to mid 2000's. I can't remember where I got it. All of the characters were small (kind of like what you'd see in a Final Fantasy game, maybe?). I think there were three attack types (light, heavy, special sort of thing).
I remember a werewolf/beast man type character, a character with a crossbow, a mage with a spellbook. The game might have been in Japanese. I remember a general impression of a green color scheme (to the menu, maybe).
Any help appreciated! I realize now how hard it is to describe a game you barely remember lol.
EDIT: Actually, it's probably Air Fortress [https://www.youtube.com/watch?v=TwL41Da9NMI&nohtml5=False] you're thinking of.
