Well, in his defense (and also to prevent another outburst) "tomorrows" could mean that there will be no more after something. It could mean that there's no hope left for the future.
If there's a "tomorrow" there's something to look forward to, so "logically" no more "tomorrows" would mean that there's no hope for the future.
"no more tomorrow" sounds like a game to end a war or something so that there's no more (fighting) tomorrow or something. but then again "tomorrows" sounds a bit weird...but as to that, any non-plural word that's been pluralized sounds weird. mooses...
What's a synonym for tomorrow? that might help...I think.
(And I'm testing the game...or should I say testing the game name...I'll test the game itself if I can find time at home.)
