Game development outsourcing,
ranked by what studios actually shipped.

By the number of distinct shipped games a vendor group is credited on in that discipline. Multiple platform releases, editions and re-releases of the same game are collapsed into one title, so a studio that shipped one game on six platforms counts once — not six times. The data comes from the same collaboration dataset that powers Collaboration Map, the Games Atlas collaborations map.

"Titles" is the count of distinct games where the vendor is credited in one of the roles covered by that page (for example "Localized by" or "Ported by"). "Partners" counts the distinct companies it delivered that work alongside — the publishers and developers credited on those same titles, collapsed to the parent corporate group, so Capcom Japan and Capcom USA count as one partner. A single game can involve several partners, so on short track records the partner count can exceed the title count.

Because outsourcing capacity is bought at group level. Keywords Studios, Virtuos or Sumo each operate dozens of credited studios and labels; ranking them separately would split one supplier’s real track record across ten rows. Every row expands into its member studios, with the services each of them was actually credited for.

Publishing and development are ownership roles, not outsourced services. Companies whose dominant credits are publishing or development are classified as buyers in the Atlas and excluded from the vendor rankings — they appear on the other side of the graph, as the partners commissioning the work.

Rankings are rebuilt from the production-credit graph as new shipped titles and credits are ingested, and cover releases from 2015 onward. Corporate events that move faster than credits — acquisitions, funding, studio closures — arrive through the Insights Feed, where you can follow any vendor or publisher on your shortlist.
