Is quake online good and what is this: Super Noah's Ark 3D
someone told me to play it but I want to know more before I make any commitments

Quake is alright. Super Noah's Ark 3D was a game made by a biblical company called Wisdom Tree. It wasn't licensed by Nintendo and the game is just a copy of Wolfenstein 3D. The Angry Video Game nerd did a review on it. It's about 14 mins into the video.

Quake Live is just Quake 3 running on flash. Sounds really neato and the game runs smooth. Unless your INTO Quake though, it's just a 5 minute experiment.

I found Quake Live to be super hard, like first training map impossible hard.
