Looks like the team behind Humble Bundle might be preparing to launch their own DRM-free online game store. Some of the games can already be purchased from the Humble Store widgets via the developer’s website or by going to a unique URL. For example:
Some of the games include Steam keys, but not all of them. Pretty cool that you can get the benefits of Steam and a DRM-free copy with the same purchase.
Some of the games are a bit overpriced though, for example Braid for $20, even though it’s half that price on Steam.
Still, if Humble Bundle launch a full store for buying DRM-free games with Steam support I can see this being really beneficial for the indie scene (for both developers and gamers).
