There are a few perks to downloading the expansion through Good Old Games rather than ModDB or Nexus Mods; anyone who already owns a copy of New Vegas can easily download it with one click, making it far more accessible to less tech-savvy players. You can pick up New Vegas Ultimate Edition on GOG right now for just $7.99. That's because there's no manual installation. It's all done automatically, minimizing user error. And what's more, the GOG versions of Bethesda Gamebryo titles come pre-patched and ready for a total conversion like New California. What Is Fallout: New California? For those who haven't heard of this incredibly ambitious expansion before, the story picks up in Vault 18, a secluded settlement in the San Bernardino Mountains that has found itself on the precipice with an aging population desperately trying to ensure its future remains in-tact. The first chapter begins on the night of the last Vault-Ball game of the season, but things quickly escalate as a "prominent figure" is revealed to be a member of the Enclave, sparking a brutal civil war within the vault. I won't spoil what happens next, but after escaping into the Wasteland as is Fallout tradition, the hugely expansive map of San Bernardino opens up, marking the beginning of Chapter 2. Throughout this segment of the game, you'll find yourself thrust into the center of a three-pronged conflict, as each major faction within the region seeks out the player "to use their knowledge, capture a lost experiment, or exact revenge for past crimes." "You will face the New California Republic under president Wendell Peterson, the New Reno Mob's Bishop Family, the remnant Shi Clans, The Enclave Leonidas Squadron, the Super Mutant Army, and the bloodthirsty Raider Alliance that have banded together in the remote Athens-Tec Uranium Mine off the Long I-15," the team promises. New California requires at least 20GB of free space, and a minimum 8GB of RAM. So, if you can run New Vegas, odds are you'll be fine picking up New California.
