When you're the size of an insect everything looks humongous.
About Super Nintendo Entertainment System
The Super Nintendo Entertainment System (1990/1991) is widely regarded as home to one of the strongest first-party libraries in gaming history, from Super Metroid to Chrono Trigger. It's a mature collecting market: iconic RPGs and late-cycle releases (which typically had smaller print runs as the industry moved toward the next generation) are consistently among the most sought-after and valuable cartridges from the 16-bit era.
