I admit that the concept of a completely open handheld console is somewhat intriguing.
What's a bit weird to me is that they say their target demographic will be children ages 6-12. Which makes some sense, cause older teenagers are very likely to have a mobile phone, which they probably use for quick and dirty gaming on the road anyway.
But how do the games exactly reflect that demographic? They talk about new, more powerful 16bit games. While the games that are on display seem like random hobby creations for the most part, which are thrown together by an individual in Gamemaker. The whole concept seems to more likely fit a cheap console for nerds, where one can easily develop games and share. I mean it's even called inDie, right. So yeah, I can see the proximity to Game Park handhelds inkBot implied.
The whole idea of giving away the console with happy meals and cinema tickets would potentially make it interesting for companies I guess, and does in fact fit the kids console pretension. Although I have to say that a basically disposable console like that would also be a very wasteful thing.
If this really is going to see the light of day and won't disappear right away either, a C2 exporter would indeed be intriguing like Jayjay mentioned. It's also a desired feature according to their FAQ: "In the future there may be even easier opportunities for game development, such as a mouse based editor. (think RPG Maker)". If that's ever gonna happen, it should indeed be Construct.
