Absolutely . The loss of the skill system was bad . The changes to the dialog system had wide ranging after effects on quest design , but it was the poor side quests that really gutted the game world . The best parts of Fallout 3 and New Vegas were the side quests . The main quest is always there but the best moments come from exploration and stumbling upon side quests . Fallout 4 had , maybe , 46 truly memorable side quests and that was it . Fallout 4 is empty compared to Fallout 3 and New Vegas . <| sep |> Ok , would someone help me out and tell me what that cableflexible black pipe is going to the end of the barrel ? Is is part of a barrel cooling system or is the a sensor at the end of the barrel that collects information about the projectile and the cable powers it ?
