Heh, while playing Fallout New Vegas again I was reminded of something I had not put much heed to in the beginning; NPCs that only exist to tell or give you something after which they run off and apparently seek to end their existence now that they done what they are suppose to do. One example is Swanick, the Powder Ganger who won the lottery in Nipton and got to go free by the Legion. After having talked to him at the outskirts of Nipton he runs into the desert, in particular to the part that is normally infested with giant rad scorpions if I had not killed them earlier for XP. Another example is the NCR ranger who gives you the emergency radio when you standing with the NCR improves which you can use for backup. BTW, I always find it amusing that he spawns out of thin air. I usually encounter him at the NCR outpost at the South West corner of the map and when my NCR reputation improves when I talk to Ghost he spawns in the distance above the slope and then drops downwards. I think NCR cracked teleportation technology. Anyway after giving me the radio he ran off and I decided to chase him as had heard from Lexx and others that this ranger tends to kill himself often after having done his task, and this time was not an exception either as he went into the hills above the NCR outpost and decided to take on two giant radscorpions which punched of his leg. It would of course be unnecessary to give these characters even bigger roles but couldn't the designers at least have programmed the NPCs to go to the closest allied settlement, the ranger for example staying at NCR outpost while Swanick tries to reach the NCR prison? Which other NPCs are also suicidal in this game after they have done their task of interacting with you?
