Honestly, I think Rockstar with GTA have the best method of revealing their games. They give a glimpse into the variety without revealing the majority. This works for an Open World game.
Rockstar thrives on variety and scale though. Even without revealing majority, they often show the key glimpses into :
"scope of the world"
"side-activities possible"
"the driving & shooting"
Which are pretty much what makes GTA stand out from the rest, except the 3rd point.
