Bundles are great ways to get a lot of gaming for little money, but if you're already a frequent patron of marketplaces like Steam, you'll often find yourself looking at bundles from which you already own one or more games. It can be a deterrent from picking up the bundle, and Valve wants to change that.

PC Games N has obtained some Steam developer documentation that says this will roll out in force before too long.

"With Steam Bundles, if a customer already [owns] some items in the Bundle, they will pay for and receive only the items not already in their account," says the documentation. "This allows the best fans of your series or franchise to 'complete the set' and get a detail on the remaining items in the Bundle."

Past Complete Packs were sometimes a bad deal for customer that already [owned] one or more of the products in the pack. Either it made bad economic sense for those customer to purchase the pack, or they just felt bad about doing so since it ]looked] like they were paying for products they already [had]. The new Steam Bundles system addresses this.

This can already be seen with the Valve Complete Pack, which costs $92.70 if you don't own anything in it. For me, it costs $15.75, because I don't own Left 4 Dead or Counter-Strike: Global Offensive.

This is an awesome, customer-friendly move that should make it that much more tempting to pick up games when the time for the seasonal Steam Sale comes up. Developers can opt to require a full package purchase instead of dynamic bundle pricing if they like, but this seems like something many developers will want to get in on.
