Steam changes - Steam bundles will be cheaper if you own some of the games

There's a big shake-up coming to how Steam's bundle purchases work, giving them dynamic pricing. In official documentation given to developers and received by PCGN, Valve have outlined a redesign of Steam bundles so that they automatically give buyers that already own some of the products within a discount. This scales based on the number of products, and is already available on some bundles in the wild, though remains officially unannounced. This also has the knock-on effect of making sure that bundles are properly discounted when their components are on timed sales.

Good stuff!!
