If they're unopened, OoT will fetch a pretty penny.
Anyway, I love the games in 2D, but they really lost me when they went 3D. OoT was the last Zelda I liked, and I do so a bit begrudgingly. I'm guessing that you're not as much a fan of the older games, though, so if they're open you might as well check them out.
