> Write your code for this game only - not for a future game.

The quote refers to a future product, one that is very likely unspecified at best, and more likely just something that an individual contributor dreamed up. Unless we have some sort of multi-phase contract, how do we know we'll ever build another thing like this again?

Markets change, hardware changes, experience changes. Hell, building this thing may show you that you should never build another one like it.

Generalize where sensible inside the project, sure. But as the quote says, build what you're building, not what you're not.
