Sure, but you've got your groups of adventure titles
Arcade Adventures - Like your Tomb Raiders
Text Adventure - Like the old Zork games
RPG Adventure - Like Ultima, Final Fantasy (which I calss as an arcade adventure, but none the less)
Point & Click/graphic adventure - Link Monkey Island.
Very true. My only point was always that classifying games that are nothing but puzzles as "adventure", and classifying games that are REAL adventure as action, is ridiculous. Adventure, as your post shows, is a very broad term, but there are some games, like most games that are commonly reffered to as adventure while they have no actual adventure, should really not be put under that category.
