Kevuru Games fits when studios have a gameplay core and need a managed path to production multiplayer infrastructure plus operational handoff artifacts. N-iX fits when a single delivery team must own multiplayer backend and live-ops stability work so handoff includes telemetry pipelines and concurrency testing. Certain Affinity fits when shared ownership across gameplay engineering and live-ops content release operations is required, because its delivery model extends beyond packaged implementation into ongoing service execution.
