BOTH these games were big parts of my childhood. (And I like them more than their respective movies too.) I remember my Dad and I bonding over playing The Hobbit on separate saves, we were racing to see who could finish the game first! Then I remember renting a game when my first PS2 broke, my dad wanted to make sure it was the system not the game, so he threw in The Hobbit. When it still didn't work, he threw the PS2 away, With the Hobbit still inside! We were both sad. Eventually, I found a second Hobbit game at a used game store, and bought it for my dad as a birthday present!
Funnily enough, when I bought King Kong, the store only had the disk and not the case (which is why it was only $2) Now I keep King King in the old Hobbit case!
To add something new, One of my other favorite obscure games is Indiana Jones and the Emperor's Tomb. I have fond memories of that game, it's my favorite Indiana Jones game!
