Line Rider

Line rider is a game that really makes us focus on the 'art' of video games.  You draw lines with the mouse or a drawing pad to create a path for the rider to ride along.  The original version is much simpler than its successors.  You are given one type of ink to draw with and physics does the rest of the work.  It is a very physics-oriented game.  

I like this game in the fact that it gives the player a creative ability.  You are not the character, but you do help the character.  This game has not goal or task to complete.  This game created alot of user videos of what can be done with some creative thinking and physics.  It is hard to relate this game to other games.
