Onesie? baby suit?
I read the words in the famous game website-gamespot. The original sentence is like this:"Electronic Arts and Steven Spielberg have teamed up to make a game that brings back the joy of that simple destruction, minus the growing pains and onesies"

I know the exact meaning of "growing pain". And I know it is a metaphor. But MINUS ONESIE? MINUS BABYSUIT? I don't get it.

I know the exact meaning of "growing pain". And I know it is a metaphor. But MINUS ONESIE? MINUS BABYSUIT? I don't get it.

Answer

I agree with Eric and that 'onesie' is American slang for a babysuit that  grows with the baby. So the answer can be added to Eric's, in that the game  is easy and grows on you.

Answer

In this context the meaning of "minus" is "without".  So the sentence could be read as： "without the growing pains and onesies".  The writer is trying to say that the game is easy to learn, in an oddly humorous way.
