Dream game concepts

I am studying for game development so it always interests me greatly to hear people about their dream games which sometimes inspire me. Logan has given some funny ideas before.

So my question to each member of the tek syndicate family, what is your dream idea

For a:

-endless budget dream game

-big budget game

-small budget game

 

If others feel like responding their idea's please do so (preferably one that has not been done yet of course)
