Also on Gamecube.

That's not true in the slightest. The PS2 is quite possibly the flimsiest console ever manufactured. I've played my Gamecube easily ten times as much as my PS2 and the thing still works exactly like it did the day I bought it (which happens to be the day it was released). My PS2 (which I only bought last summer) on the other hand, has stopped playing most DVDs, and I expect it to stop playing PS2 games, PS1 games and audio CDs entirely within the next few months. On top of that, the console itself is the hardest of the three to code for considering it uses three weaker-powered processors instead of one higher-end processor, so the "software" argument doesn't work there either. Sony doesn't even have an internal development group. In other words, they don't even make their own games anymore. The thing is just a hunk of crap with a lot of 2nd and 3rd party support.

The reason that Nintendo is the best at what they do is because they've been doing it for about a century. They've been making video games for about 20 years, but have been in existence since the early 1900s. They know exactly what their audience wants, and they never fail to disappoint. The day Nintendo stops making video games is the day the video game industry ceases to exist.
