You have to pick:

Anybody realize that you are essentially God if you a formless consciousness that exists for eternity. You can't interact with anything tangible, but you can always imagine a universe.

@ jonathanost
Except you are not omnipotent. You are limited by your mental capacities. Sure you can imagine a universe, but it won't be real and you can only imagine a universe as good as you could do it right now, which is pretty limited in scope.

So I'm not a very capable god. I don't see any others around so that should be sufficient to satisfy me. Especially once I've gone mad. :)

In my opinion this is the worst option on this site.
