Chris (Obsidian): New ammo. Gambling. Wayne Newton. A dinosaur with a gift shop in its belly. Rockets. Companion quest arcs that change their perks and their attitude. Calling death beams from orbit. Faction politics, both violent and passive. Confronting a situation where you choose the bad guy…even if the bad guy is everyone. More than one critical path. Survival recipes. Mantises. Geckos. Modding weapons. Traits.
Chris (Obsidian): There are a number of makeshift weapons you can make in New Vegas at reloading benches, campfires, and workbenches… but not just weapons: ammo (including homemade flamer fuel and recycling energy weapon ammo), poisons, doctor bags, explosives, and even Survival crafting recipes using food and hides you scavenge from Wasteland creatures. The Doctor Bag creation in hardcoe mode especially is helpful, in terms of some of the weapons, however, some of the classics are making a come-back including Bottlecap Mines, you can also make Time Bombs (req: Explosives 50) out of Duct Tape, Dynamite, an Egg Timer, and 2 pieces of Scrap Electronics.
