It’s the ClientRegistry.blob file. It sits right inside the Steam installation folder and is also one of possible fixes for any Steam woes (“Delete ClientRegistry.blob” sits right next to “Restart Steam”). Long story short, some people have written an application that disassembles the file in such a format where you can look at the various Steam ID entries (even upcoming ones sometimes, or deals that never happened like Neverwinter Nights, Supreme Commander 1 and its expansion and A Vampyre Story, as examples of those) or game packs. So sometimes you can use it as a crystal ball showing you upcoming but unannounced titles. It’s just that it’s never 100% precise, since some deals just don’t happen and some deals don’t get added to the registry beforehand they’re actually released.

Hard to say. Based on the pricing of the other packs, £4 for 5 games, that would make it £12, but that seems way too low considering there are two high profile recent releases. Super Meat Boy alone sells for £12.

I might be wrong, but I think the PC version was self released. There isn’t really a perfect definition of “indie game” anyway, but you do raise a good point.

Of course none of what I’ve just typed calls into question the veracity of the list. It’s just Lumines is an odd choice for ‘Indy’.
