The Legend of Zelda: A Link to the Past - I never owned this when I was younger, so my time with it was made up of borrowing it from my cousins or renting it. I never actually got to finish it, although I watched my cousins do so. This has been a regret, which I hope to rectify using the SNES Classic one day.
Super Mario RPG - Same story, really.
The Legend of Zelda: Majora’s Mask - Never owned it, but liked it quite a bit when I rented it. I don’t know why I never asked my parents for it or spent money on it, because I did like it a lot and loved OOT. The same was true of Banjo-Kazooie and Banjo-Tooie which I’ve never played. (side story: I bought Banjo-Tooie years later, when I got a used N64, as I’d sold mine to fund a PS2. I left the cart on the counter and it ended up disappearing. I haven’t seen it since so I think someone stole it.)
