"The glory is yours to claim, for that is the wages of war."
The above line feels so natural to me, but someone pointed out they thought it would be grammatically correct to use one of the below options, all of which just sound odd to me:
"The glory is yours to claim, for those are the wages of war."
Doesn't sound right to me because "those" isn't the word I would use to refer to "glory."
"The glory is yours to claim, for that is the wage of war."
Also somehow sounds wrong when I think about all of the ways I hear the word...
"The wages of sin is death."
and I've never heard anybody say "...a day's wage." It's always "...a day's wages."
Also, I'm a little biased because this is for a script for a board game I am designing, called "Wages of War."
Is the first sentence really incorrect? Nobody I showed this to said anything about this until after I got the voice-over recorded, unfortunately. Knowing that this is the title of the game, is that justifiable reason to leave it being that it's really a play on the title?
