Stuff like Zelda and Metroid. There are a lot of games that are inspired by them or similar, but there are so few pure adventure games. Fight monsters, solve puzzles, unlock new areas by acquiring new abilities. Most games these days focus so heavily on the combat; if there's shooting, it's all about shooting--if there are swords, it's all about hacking up monsters. But not a lot of people seem to do it like a simple Zelda or Metroid game. Just an awesome adventure where you explore and get new stuff to advance.
Maybe it has something to do with the fact that a true adventure game requires a great amount of planning, whereas it's so easy to just focus on the combat and throw monsters at the player until the credits roll. It's frustrating, though. Nintendo is like the only publisher interested in this sort of thing, and you know long they like to take on making their games. I just wish more people would get in on it.
