I didn't think the two phrases communicated the same thing, but now that you mention it I can see how it does.
What do you mean by "...a detail of the game..."? are you just referring to an aspect of the game, or something in the tone, etc?
I guess just an interesting fact about the game? Something about its story, or its mechanics, or anything really, as long as it's not obvious. So if I say my game is a puzzle platformer, that's pretty boring, but if I say it's about the struggles of a ghost trying to be an adult, that's a lot more interesting.
