This is a great answer. Before listening to Collector’s Quest, I had only really explored game collecting on the surface. Without context like this, it’s easy for some to wonder why NES may be king, and simply write it off as nostalgia. But when you really start getting into the weeds of the hobby, you see that NES mimics other pivotal points in other hobbies that collectors gravitate towards. Sort of how there were other comics before Superman and other iconic DC and Marvel heroes, but those icons, like the NES, seemed to be the impetus toward something greater (this coming from a guy that will die on the hill that Atari is fun to collect for despite many people writing it off these days). SNES continues with that momentum and builds upon it, but NES is interesting for the reasons previously mentioned.
One category of games that interests me in the NES library is games that were ported from home computers like the Amiga, Atari computers, and C64. Castlequest, North and South, Ultima, etc. The SNES got computer games too, but the NES ones interest me more just by sheer fact that they attempted it at the time. The PAL-exclusive port of Elite is something I really wish we got over here in North America.
