Maybe old news to some but some may find it interesting

I just came across this article from GDC 2011 and at first it made me chuckle.

But after thinking about it a little it makes me a little sad to know that a company like Rovio can produce a game like Angry Birds (which had achieved approx. 100 million downloads at the time) and not credit the author of the Box2D physics engine it uses as it's core until he confronted them about it.

Even now after doing a google seaarch of the Rovio site there is still no mention of Box2D or it's author Erin Catto, which I find disgraceful.

I saw credits to Catto inside the Angry Birds Space from 2012...

@Scouser so what you are saying, is that every game released using Gideros should mention/credit @atilim?
I think companies like Rovio are trying to hide the used technologies as much as possible, for different reasons. And isn't its their right to do it?

I don't say that it is good/wise, no, it is ungrateful and ugly, and Catto could be a millionaire right now if box2d was not for free. But mentioning every author of every technology we use in credits, would be an overkill.

at the other hand i dont think so there is any 2d game developer living in this world who doesn't know about box2d

@ar2rsawseen: What I'm saying is that somewhere they should have mentioned that they used Box2D given that without a physics engine they couldn't have written Angry Birds. If they had used Havok, they'd have had to pay a license fee & credit Havok in the games.

Frameworks work differently as most (but not all) apps developed using a framework mention the framework or show the framework logo as a splash screen. This is usually part of the license agreement for some of the bigger frameworks (such as Havok).

Maybe I'm old fashioned but if I use a library which is a core part of my app then I think it deserves a credit in the same way that artists & musicians / SFX designers should be credited (if known).

Well, the beer framework is a bit smart about this and they do not want you to credit, but if you want them to talk about or consider your app for the app of the week/month then you need to add them into the credits and also place their logo on your website.

It is nice to be credited if someone uses your code/framework but then again if you pay for it, it should be entirely optional. Still a lot of frameworks and other controls/etc insist that you give them credit.

just my two bits...
