I can't believe some people actually spent 100+ hours on New Vegas. That's absurdly high to me, because I breezed through the game and spent about 30 hours total on it. I did some side quests and I explored but I basically followed the main quest through to completion because it was the most interesting thing to do. I don't feel like I missed anything and I only played for 30 hours. To you 100+ hour people, what are you doing all that time? I talked to everyone I encountered, everyone, and I never got lead on any exciting or epic quest lines because of it. Occasionally it would trigger a side quest, but nothing crazy that would have me playing for 100 hours. I also explored every nook and cranny of an area before moving on. I didn't uncover the map just to uncover it though, I had to have been doing something to be there in the first place.
I don't see the point of picking a spot on the map and going there just for the sake of exploration. I'm not here to just explore the map. The game should give you some reason to go there, like a quest that sends you to the far corners of the map. Since it didn't happen like that I did end up missing out on a few locations. But again I ask, what did I really miss out on by not going to Jacobstown? Was there 70 hours of content there or something? I don't get it. To me, Fallout: New Vegas was short.
