At its best, Fallout is a series that inspires players and shows what a western RPG is truly capable of. Many argue that the pinnacle of the series is Fallout: New Vegas. Released after Fallout 3, it had sharp writing, an engaging story, and well-received features. In fact, several of its innovations streamlined players' experience in a great way compared to Fallout 3. Developer Obsidian would later go on to create The Outer Worlds to prove itself a master of this style of game once more, but Fallout: New Vegas was where players first noticed this expertise at work.
A lot has changed since Fallout: New Vegas was released. Most recently in that change, Bethesda was bought by Microsoft. This brings Obsidian and Bethesda under the same umbrella, opening up the possibility of a new Fallout: New Vegas title. This is something many Fallout fans would love, and some think Fallout: New Vegas 2 could save the Fallout setting. The point is driven home by the fact that New Vegas is still so beloved today, 10 years after its launch. For its 10th anniversary, New Vegas can once more celebrate being the most acclaimed Fallout title.
A lot of Fallout: New Vegas' staying power can be attributed to its robust systems and replayability. Players can play through it in different ways each time, aligning with different factions and building their characters in new ways. On top of that, it features a Hardcore mode for anyone wanting even more challenge. It speaks to the love players have for the game when they are debating whether Fallout New Vegas is better than The Outer Worlds. Remember, The Outer Worlds was created by Obsidian almost 10 years after New Vegas, with better technology and more experience. That there is a debate at all speaks to New Vegas' enduring quality.
As for a potential sequel to New Vegas, it's definitely within the realm of possibility. The Microsoft/ZeniMax deal makes New Vegas 2 a tangible thing by uniting Obsidian with the Fallout license once more. Of course, such a sequel doesn't have to take place in New Vegas again so long as it continues the story line somehow. Some think that Fallout: New Orleans would make the perfect follow up.
On the other hand, there's a good chance the two companies won't work together again. The history between Bethesda and Obsidian is not a pretty one, and the whole Bethesda-Fallout: New Vegas controversy is well documented. Still, whatever comes next for Fallout or Obsidian, 10 years later and no doubt beyond, Fallout: New Vegas is still good.
Fallout: New Vegas is available for PC, PS3, and Xbox 360.
