In the longer run, however, with the NES near its end of its life many third-party publishers such as Electronic Arts supported upstart competing consoles with less strict licensing terms such as the Sega Genesis and then the PlayStation, which eroded and then took over Nintendo's dominance in the home console market, respectively. Consoles from Nintendo's rivals in the post-SNES era had always enjoyed much stronger third-party support than Nintendo, which relied more heavily on first-party games.

Historical aspects of the Expo line route are noteworthy. It uses the right-of-way for the Santa Monica Air Line that provided electric-powered freight and passenger service between Los Angeles and Santa Monica beginning in the 1920s. Service was discontinued in 1953 but diesel-powered freight deliveries to warehouses along the route continued until March 11, 1988. The abandonment of the line spurred concerns within the community and the entire right-of-way was purchased from Southern Pacific by Los Angeles Metropolitan Transportation Authority. The line was built in 1875 as the steam-powered Los Angeles and Independence Railroad to bring mining ore to ships in Santa Monica harbor and as a passenger excursion train to the beach.
