It's an illusion that creates an object of want, vague in it's description which is mainly what I like.
Alright, so, the questions are:
1. The object of want, am I the one who guesses what that something is, be it a person or a actual object, or is that something that the opponent himself thinks? I'm just wondering if this allows us to have a sort of access to our opponent's mind or not. Basically, do we chose the object or is my opponent the only one who actually knows it?
2. The snare that catches my opponent, is it an illusionary snare or is it a trap that we set beforehand? Or do we set it mid-genjutsu (and the genjutsu also allows you to hide yourself from your opponent's sight)
