There is a game to memorize the fretboard. As it turned out, memorizing the fretboard, while somewhat useful, was not what helped me see music on the fretboard. My guitar teacher is responsible for that insight by insisting I focus on the relationship between notes, and over many songs. Where C is on the guitar neck is nowhere near as important as the fact that the C I am playing is a minor third to the root note I will end the phrase on. His insistence was mysterious to me until it finally clicked. This is why a video game will never replace a teacher who understands the end place of wisdom they are trying to bring you to.

It's a useful point to consider just how little or how much video games can cover. If video games can only ever be the most effective route to learn 10% of what we need to learn, then that's less interesting to spend time and energy on compared to if the number is 50% or 80%.
