I'll say 64, though I'm curious to see how replaying it in 3D All-Stars may affect my perception of it. After that I'd say it goes to Odyssey, followed closely by 3D World. Galaxy is a great game as well, and 2 by extension. 3D Land was great for being a handheld entry and I enjoyed that quite a bit. Sunshine is my least favorite mainly because it felt a bit unpolished when I initially played it and at the time I felt like I was going through a phase where I didn't really enjoy much of Nintendo's output as much as I did during the N64 years. Like 64 I'm wondering how my feelings on Sunshine will change when I play it again in the upcoming collection and whether it will affect how I rank everything.
