One of the reasons I am a fan of the Humble Bundle and a repeat buyer, is the fact that it always offers Linux ports of the games sold.
With that in mind, Imagine my surprise, when I found out that games that were already sold in the past via the bundle, do not offer the Linux ports when they are sold via the Humble Store.
Case to the point: Limbo. I have the Linux port. I bought it via the Bundle. But I can’t recommend it to my Linux using friends because they have no way to get it now that the bundle is done with.
