That is not exactly correct. Bad games can slow down adoption, limit word of mouth, finally delay developing new features and content till the base game is patched up to standard. All these things are different to quantify, but the same can be said for a lot of marketing budgets being spend.
You can even make a case that experienced QA dept. will speed up the development during the final phases - I always remember the article talking how South Korea is recognized as the second-fastest country globally in constructing nuclear plants, averaging just 56 months per plant, compared to the global average of 190 months. That has been attributed to a core construction team working together for years or even decades.
