Steamゲームのサントラやサポーターパックの販売は“やり得”とのアナリスト見解、コストほぼゼロなので。実はValveもおすすめしてる - AUTOMATON

This page discusses analyst Chris Zukowski's insights on DLC sales strategies for Steam games. He recommends releasing small DLCs like soundtracks and supporter packs on launch day, as they have minimal production costs, face little user backlash, and reliably generate profit. However, he advises against releasing substantial DLCs simultaneously with game launch, as this creates the impression of cutting content. Zukowski's analysis shows most small games lack DLCs, representing lost opportunities. Notably, Valve endorses similar strategies, recommending developers create soundtracks and bundles due to minimal effort required. Overall, small DLCs represent low-risk revenue generation opportunities.
