Gameduino (or how a $5 chip can outperform an Amiga :( )

[HenryCase]

Get a Gameduino? Nah. $53 is a rip off for what you get. I'd much rather pay $25/$35 and get a Raspberry Pi:

I'm raspberry Pi's biggest fan, but the Gameduino is a totally open game platform, no need to spend a year learning posix and OpenGL just to make a blob move across the screen... Plug it in, program it and go

You don't have to learn about POSIX and OpenGL to program a game on Linux. For example, could use KidsRuby (which was recently featured on the Raspberry Pi blog) + Gosu. Take a look:

PyGame is also very popular for getting started with making games:

There are tons of libraries like Gosu and PyGame that make game programming easy. Plus, the advantage of using libraries like that is that by the end of it, not only have you got a game, you've also taught yourself a versatile programming language for more practical tasks.
