Oh, sorry, did I say "money"? Hmm, yes I did... Well, I meant "resources" .. :P

Anyway, I see your points. However, I still don't see them as reasons to why I would be annoyed by devs making statements that they will make a native Linux game targeted for Ubuntu

And yes, of course you are right, this is not the start of Linux gaming, that started ages ago (Must never forget Tux Cart). But please, you know what I mean ... oh, you don't?
Oh, Desura recently came... now Steam is coming. Unigine Engine ... Unity 4.0 ... Nvidia finally starting to push out proper drivers. Not to mention all the articles that are gaming-related here on Phoronix.
Obviously, SOMETHING has started just recently, or at least picked up a substantial pace
