Topic says it all.
Personally, I think it should be based on what type of person your character is and who you are siding with in the main quest. For example, if you are siding with NCR, then you can't send the nukes at them or you will gain a HUGE amount of infamy. For my NCR follower, he/she was good natured and didn't want to bring more nuclear devastation to the world, so he/she sacrificed LR ED-E instead to stop the launch. If you follow the Legion in the main story, maybe you wanna screw over the NCR even more, so you let the nuke drop on them. If you follow Mr. House, maybe you're a good guy and don't wanna hurt more people than you have to so you stop the launch, or maybe you're an evil psychopath and you wanna launch the nukes at both NCR and Legion. Again, I think the decision should be based on who your character is and how they behave, as well as who you are siding with in the main questline. However, if you are not interested in the story and just in it for the goodies, and you are following House or Yes Man, then nuke both and you have access to both Long 15 and Dry Wells. If you are just in it for the goodies and following NCR, nuke the Legion. If you are following the Legion, nuke NCR. 71.171.112.74 17:03, October 14, 2012 (UTC)
