Has this been done before?

Where and how would you see a cursor coming into play here?

[Gshonk]

Well instead of having like certain input (like press X, Y, Left buttons) you would have certain movement that you would have to emulate with the cursor or maybe draw lines for movement or to block things. Or you could have it where the cursor is the attention of the player so you would have to draw their attention away from the people they were going to kill.

Just some random thoughts, kind of makes it more like a point and click adventure game I guess.

this sounds like a really deep game
