The first thing when the time comes will probably be a Zero Suit Samus with her Yellow Whip as the main Character.
When I first saw Samus in Smash Bros. Brawl use the whip I thought to my self, Now there is an idea for the future.
That was about 10 years ago now. Lol.
I am going to try and build one, I just have to hope I don't make a Sonia Sprite by accident. They are fairly similar.
I have some basic ideas at the moment but not much planned. Right now it's Trial and Error.
Dawn Aran (Probably Not)
Most of the ideas are still in concept, Nothing is absolute yet.
And of course, Importing the complete Metroid Nes Soundtrack into Castlevania.
Wishful thinking, Importing the Metroid NSF in.
