Saying third parties weren't a key for the NES/SNES is written by someone who clearly was too young or not even born when the NES/SNES were out, lol.
The breadth of games was the no.1 reason the buy the NES back in the day. Sega had great games on the Sega Master System, everyone liked their arcade games, sure, but you didn't want to get stuck with a Sega because it didn't have all the games the NES did (good or bad, that meant Ninja Turtles, Batman, Metal Gear, Castlevania, Megaman 2, Blades of Steel, etc. etc.).
Nintendo has basically become Sega of the Master System era, basically trying to sell a platform on their own games, whereas the 360/PS3 sorta have morphed into the modern NES (widest variety of games, all the developer support).
