Gameplay Part 1 the skill sets

Now this is my favourite part of fallout New Vegas and it is what separates it from any other game, first of the skill sets: Barter helps with making deals and gives discounts in stores, Energy weps helps with damage and accuracy with these weapons as well every weapon requires a base level in order to use it properly such as a plasma pistol requires a Lvl 20 in this skill, Explosives allows use of explosives properly be it grenades or launchers and also gives crafting explosives at a workbench, Guns, same as energy weapons but use bullets not batteries, Lockpick allows for opening locked doors and loot containers, Medicine gives you medicine buffs such as more healing from the games medkits called stimpacks, Melee weps are same as other weps but while using objects such as baseball bats and golf clubs, Repair is for repairing damaged weapons and Armour as well as crafting many items in the workbench and ammo bench, Science is for hacking computers and making medical supplies, Sneak allows stealth movements and when using stealth armours or stealth gadgets, Survival is food based and making poison and edibles in campfires, Speech is used for manipulation of individuals whether it be discounts or information you couldn't get otherwise, Unarmed is similar to melee but it uses your hands whether it be power fists or brass knuckles or if all else fails your bare hands.
