This is a really cute story. It might be really nice to fix it up and play it with your brother at Christmas (or other similar holiday) as a bonding fun time.
For my kids, I'm not sure the Micro Genius era of games holds up to the sandbox style of say Goat Simulator or constant chaos of Fortnite. Bit of a shame. In hindsight, I should've walked them through a bit of history of gaming in sequence.
