As game companies begin to regain some sense of sanity a week after E3 2009, some are starting to send reactions to the event.

Located at Booth 500, Gamepark Holdings Co., Ltd., was demonstrating its latest open source handheld game system, the GP2X Wiz.

Here’s the company’s reaction to E3 2009…

Korean company Gamepark Holdings Co., Ltd., has released the GP2X Wiz handheld game system and… what, you though Nintendo’s DSi was the only new handheld on the block?

The Wiz will be offered early May 2009 in the US through various web sites – although it is available now on the GP2X Store – for $179. Part of the excitement surrounding the system is that it runs on Linux and will have an open SDK, meaning just about anyone can make games for it.

I’ve been toying with the Korean game system for about a week and I’m pretty impressed. And by “toying” I do mean more than just playing games. Here’s a look at the hardware, the games mine shipped with and some initial impressions.
