I have been thinking for a few weeks now "Why doesn't somebody make a game where you actually play as a vampire?"  One night, I must have been awake for an hour or two thinking up a game, and I went into a lot of detail.  I have a lot of features in mind.  Originally, I was thinking of a 2d platform game for the DS.  But, better yet, I thought, would be a 3d platform-ish game for the PC, like Assassin's Creed, or the new Prince of Persia.  I think this could be a great game, if anyone could make it, but I don't know how to cast the idea to a game developer.  I figured here might be as good a place as any to start.

Some of my ideas are as follows:

1.  Have equipable items.  Since you would be playing as a vampire, there would probably be some sort of sun/light penalty.  Well, what if you could go to some shop, and buy a hat to protect you from the sun?  Of course, it would be easy to go get a hat to protect you, so there should be some penalty for that, too.  Maybe it would slow you down, so you would want to take it off whenever possible.  I think the number pad would work well as an inventory controll.

2.  Be able to level up your character, like an RPG.  As you up levels, you could buy better abilites, for instance, turning into a bat, to get around the map faster, or after you advance to a higher level, you could perhaps turn into mist, to get around quickly, and be able to get through air-vents, etc.  Of course, there would be the obvious addition of having different level weapons.

3.  And this is one of the least-used things in most PC games, but it should be used more.  Have any of you played Battlezone 1 or 2?  Not the arcade game.  The PC game.  You can control units.  I was thinking for this game, perhaps if you bite someone, they turn into a vampire, and could then be controlled by you.  Tell them to go somewhere, attack this person, etc.

I have some more ideas, but those are the basics.

What do you guys think?  More importantly, is there any interest by the Stardock devs?

Please tell me if you think it's a cheesy sounding game.  Give any feedback you have, as long as its intelligent.  No "That's the dumbest idea I've ever heard" comments, in other words.
