My ideal game would be open world where you get to choose the look and gender of your character, you have a huge open world and can literally do anything you like and full exploration, but as you explore you find the game does have some kind of theme, there's hidden briefcases all over the open world with clues and you have to find things.
There would be absolutely no combat but it's the exploration that will be the thing because the game won't tell you what you are supposed to do, you have to figure it out for yourself.
