I’m sure you’ve seen it a million times, but here it is again… Line Rider!
Created by Boštjan Čadež in 2006, Line Rider was a simple physics toy. Its line-art graphics weren’t anything new. If anything, they were almost nostalgic for old, primitive, black-and-white bitmap paint programs. And its sketchy illustration style had been used on plenty of older projects. But the combination of physics with the ability to draw the world itself was new. And its addictive fun encouraged people to create and share their worlds. And it launched a whole new style-genre of sketch, or doodle, interfaces for games.
Among the most recent of these is Sketch Nation Shooter, for the iPhone. Take a look at their blog to see examples of how users have created their own games with it. It’s a great example of user-generated gaming — even if it’s only the artwork that can be changed, and not the unerlying physics and game rules.
There’s an accessibility to the hand-drawn style that makes it feel very democratic. It invites play and interaction. Perhaps that’s why it’s also used to encourage discussion on more technical communication such as web design wireframeing.
Below are a handful of other games of this style: Your Doodles are Bugged!, SketchFighter, Jelly Car, and Doodle Jump. Also interesting, but not shown, are Doodle Army, Doodle Blitz, Doodle Blast , Doodle Games, Doodle Fly, Doodle Bomb, etc…
