"No, it's not. Just because not many have managed to make a living with it yet, doesn't mean it's the fault of the tool"
C2 is great tool, that helps easily unleash creativity, but... what are the real monetization methods for C2?
on AppStore you can sell apps but it needs investment (dev account + Mac + some test iPod/iPad/iPhone);
but what about Google? it has lots of users that are not willing to pay for anything - so you can put small AdMob banner via MoPub via CocoonJS. And that's all - what about native support for ads? Full screen? Interstititals? High eCPM stuff... (and adding other SDK via Eclipse to slow PhoneGap is not any solution, bc it's slow).
So from perspective of serious monetization methods - for now C2 is hobbyist tool. You can say that a few developers earns hundreds of $$$, but hey - look at download counter: over 639,000 C2 downloads... Over 639,000 downloads and no mobile ad network is treating C2 serious (= make plugin)? [I know that it is not the same league, but almost every ad network supports Unity and none supports C2, so Unity is seen as a professional tool and C2 is seen as a toy for kids?]
also issue of compilation: on Android you can use slow PhoneGap or put Ludei logo everywhere...
