This paper responds to a 2016 systematic literature review of the research on learning games by Ke (2016). The review paper unpacked the idea of intrinsic integration in learning games, analyzing important emergent themes. The key ideas and the value of this review are discussed in the context of the recent shift to virtual instruction. The limitations, impact, and future implications are also described, with the perspective of this response focused on education theory. Intrinsic integration is an important consideration when designers create the next generation of digital games, and as researchers try to untangle the affordances of different educational games for student learning.
