I'd say play the older Link games to obtain more knowledge of what goes on in Zelda. I find ALttP is a little more interesting since it's a bit more colorful and...I don't know, it just seems more interesting. And then you must play OoT since it's the first 3D game of Zelda and it's cool! And then play TP (But that's not an older game, hehe.).
