I have never played these games. Should I buy the collection? I thought Odyssey was great.
The games are amazing and very important in the history of video game evolution. Mario 64 set the rules for all 3D games, which are still followed today. Sunshine is a great game with a few frustrating parts that gets way too much hate, ad Galaxy is damn near perfect. Having not played any of these, I think they are great history into gaming, to kind of show you how they started in 3D and evolved over the years. They are absolutely worth it, as long as you know they do have their flaws especially Mario 64 given its age and being the first true 3D game of its kind.
