the.com/name of the game

means The core objective or the single most important factor in a given situation — the thing that actually determines success.

from A 20th-century idiomatic phrase built from plain parts — 'name' plus 'game' — using 'game' in its old sense of a venture, business, or pursuit with rules and stakes, not just a pastime. Calling something 'the name of the game' casts the whole situation as a contest and declares what winning actually requires. It shows up in English print by the mid-1900s and spread fast through sports talk and business jargon, which is fitting — both worlds love pretending everything is optional except the one thing that isn't.
