I only had a Struggle64, too. Renting games at Blockbuster in-between Rare and Nintendo games was the definition of a crapshoot. Lotta Fighting Force 64, Glover, Fighter's Destiny, and yes, Superman 64. Every so often you get a jewel in the rough though, like Mystical Ninja/Goemon's Great Adventure, Mischief Makers, and Star Wars: Rogue Squadron
adding 64 to the end of all the game titles made it seem generic. Like they were the gaming equivalent of those bags of cereal on the bottom of the shelves at the store.
