Is it okay to use "it's not also the fastest in the game" without using "no longer"?

While "it's also not the fastest in the game" does make sense grammatically, it does not express the same meaning as "no longer." "No longer" implies that something once was but isn't anymore, which is the meaning the speaker wants to express here. The speaker states it was once the fastest in the game but isn't anymore. Thus, instead of "it's also no longer the fastest in the game," you can say "it's also not the fastest in the game anymore" to maintain this idea. Ex: My baby brother was born last week. I'm no longer the youngest in the family. Ex: The milk expired last week! It's not safe for consumption anymore.
