The author didn’t use those words “just because”. Game-based security and simulation-based security are two different styles of security definitions used in cryptography, and we differentiate between them for good reason: game-based definitions are typically weaker (in that they capture less adversary behaviour) than simulation-based definitions.

Also, they have nothing to do with “video games” or physical simulations therein.

Thanks for the hint. Reading more about this, it seems the crypto/zero-knowledge/interactive-proof terminology is formal but overloaded here.. games that have nothing to do with game-theory, simulation that has no connection with bisimulation
