There's a simple reason Nukes weren't used. Because they're boring! That's why.
I like this logic
'press X to nuke' is boring compared to shooting aliens.
The use of nukes in Reach wouldn't have impacted the gameplay; they would've been used on ships.
Yeah but the lack of nukes allowed the writers to shoe-horn in some fighter space combat and some marine boarding action. So I'd say it affects game play.
So now I'm not sure what point is being made here. We were discussing whether a 'no nukes' order was given.
No, you were discussing how it made no sense that Reach didn't have nukes to use instead of the slipdrive op that appears in the game, that is you said <<Lib, you cool dude, the Spartans in the campaign explicitly said that they wanted to use nukes on the Covenant, but that all their nuclear capability had been taken out.>>. To which I said there's a reason they didn't have nukes, because nukes are boring. You countered by saying Nukes wouldn't affect game play because nukes would only be used against ships (ie situated in space). To which I say that clearly the presence of nukes would affect game play because then the slip-drive operation arc would have no place in the story and there would be no space combat and no covenant-ship assault, etcetera.
Or in other words, the lack of nukes was problem put into the story for the sole purpose that the Spartan team would have a reason to go into space, fight in combat spacecraft and assault a covenant corvette. Because if they did have nukes presumably they could just nuke the enemy fleet into oblivion or whatnot.
