The virtual console is now offering GameCube titles. GameCube/PS2/XBox was the tipping point when most major 3D releases looked reasonably good and the hardware was strong enough that developers were encountering fewer limitations that hampered the games in very fundamental ways. Compare Resident Evil 1 on the Playstation to the remake one generation later on the GameCube to see a very direct example of this.

Additionally video games can be a major time investment. Disney doesn't worry about the older Star Wars movies cannibalizing interest in the new ones because you can match the original trilogy in a single evening, were beating a single game could potentially take months. The quality of the entire Zelda series on average is extremely high and the majority of the games are still worth playing, a young gamer could easily start going through the library and find themselves having enough fun to just keep focusing on that instead of purchase the latest and greatest at top dollar.
