Fallout New Vegas

* There is an optional hardcore mode, the character needs to drink water, ammo has weight, healing isn't instant etc. Normal mode is more similar to Fallout 3 gameplay.
* The storyline is focused on the New California Republic vs. Caesar's Legion vs. New Vegas residents.
* You are not a vault dweller but are given a Pip-Boy by someone who is one.
* There is a screenshot of a vault suit as well.
* There is an assault rifle looking like the M4, as well as a new big gun with a backpack, held like a minigun.
* There are special moves for melee weapons in VATS - specifically a move for a golf club called "Fore" which seems to be a groin shot.
* The Hoover Dam is in the game and is supplying electricity to the city.
* There is a quest to rescue a ghoul from some super mutants. The ghoul can then become your companion
* The Geckos are back.
* There are both dumb and intelligent super mutants, including the elite Nightkin.
* Some super mutants look similar to the ones in Fallout 3, while others are new. There is e.g. a female super mutant with a 1950s hairstyle who apparently is one of their leaders.
* Screenshots include a guy with a beard and straw hat, a ghoul an NCR Ranger
* The only picture of New Vegas itself is concept art and not a screenshot
* Some location screenshots include a huge model dinosaur advertising a hotel, some satellite dishes, an array of solar panels
* A character generation shot showing a "vigour machine" instead of the skill book
* NCR base is the McCarran Airport, Caesar's Legion is based in the Vegas Strip, while super mutants are based in a place called Black Mountain. There is also a town called Fremont and another called Primm. A topless reuve is mentioned as being in the latter. Area 51 also appears.
* NCR Ranger armor is similar to a brown combat armor with sleeves, there are concept arts of a Ranger
* Skils have a bigger effect on conversation choices. E.g. someone with a high Explosives skill may be able to have a coversation about explosives where appropriate.
* There is a Reputation system in adition to Karma.

* The Brotherhood of Steel is back, but the core story revolves around the NCR and Caesar's Legion.
* SPECIAL now has descriptions - eg CHA 10 = Cult Leader, EN 1 = Basically Dead.
* Those descriptions for Strength: 10 - Hercules' Bigger Cousin 9 - Doomsday Pecs 8 - Circus Strongman 7 - Beach Bully 6 - Barrel Chested 5 - Average Joe 4 - Lightweight 3 - Doughy Baby 2 - Beached Jellyfish 1 - Wet Noodle
* You get a Vault 21 jumpsuit from the doc who revives you, along with a pistol and a Pip Boy 3000.
* Weapons can be modified, but modifications only have positive results. The magazine implies you won't need to make a choice between different mods, because they won't be mutually exclusive.
* And a little later the magazine contradicts itself by writing that adding a larger magazine increases reload times.
* Every weapon has a special attack, not just the golf club. It seems that Fore! does not mean groin shots are back for every weapon.
* Guns have different knockback amounts, pistols don't do much, shotguns blast people away.
* There's a town-specific reputation, and Obsidian has 'hinted' that the reputation will impact endings.
* Karma has been overhauled, tracking the factions and ideologies that you agree with.
* Nightkin are back, as blue-skinned Super Mutants who've gone schizophrenic through Stealth Boy use. They attack you while cloaked, deactivating cloak at the last minute to hit you with a club.
* The Tabitha situation can also be resolved by convincing Tabitha to revolt against the other Super Mutants.
* Helios One is not only a power plant, but also the location of the controls of a solar weapon developed by Poseidon Energy which you can employ yourself.
* You can now choose the main character's age.
