The article is misleading, there isn't an achievement for doing this, but it adds up to part of 2 achievements. the 30 onyx medals and all onyx medals and level 100 achievements.
[/quote]Wrong, this construction was for getting an Onyx medal. It does lead to getting the achievement for all Onyx medals, but the one for getting 30 Onyx medals is also a medal and not an achievement. However, there would be an achievement for doing this
if no other Onyx medals have been previously obtained. But yeah, it's misleading.
There's more wrong with the article. It mentions how it averages 34 button presses per minute. That number was simply derived from dividing 2000 by 60. If you watch the vid, it's more like 120 presses per minute.
Still takes more than an hour, not every piano "play session" counts towards the medal. More like every 3-5 times you play it.
Right, especially for the easiest one in the game. I was more impressed by the robot I've seen once, it was built by some guy to help him play matches in PDZ for the 1000 ... matches played achievements.
