Well, I'll say yes, but it all really depends on what kind of games you like, such as gameplay. If you loved the gameplay on the Gamecube version of Twilight Princess (if you played it), then you'd like OoT's gameplay. I'd prefer getting it if I were you. It's one of my favourite games, and that goes with most people. It's said that it's one of the most favoured Zelda games around. =P
About what? Why not you looking at walkthrough section of this site. It really helped me when i playing that games...
I'm sort of confuse why you mention changing your profile. What are you changing. Also, the gamecube is good, but its better to get a wii. You can still play game cube games on the wii and download previous console games (means more zelda). I've beaten every Zelda game.
