The 2000s were a golden age for PC RPGs, with several landmark titles that reshaped the genre. Based on critical acclaim, sales, cultural impact, and fan legacy, here are the Top 5 most popular PC single-player RPGs from 2000 to 2009:
5. Diablo II (2000)
Developer: Blizzard North
Diablo II refined the action RPG genre into near perfection. Its fast-paced hack-and-slash gameplay, randomized loot, deep character customization, and addictive item grind made it incredibly replayable. The gothic art style, atmospheric soundtrack, and tight gameplay loop kept players coming back for years. It also pioneered online multiplayer via Battle.net, encouraging a strong community and economy around rare items. Whether solo or online, the game hit the sweet spot between simplicity and depth, becoming a benchmark that countless ARPGs still try to emulate.
Despite being released in 2000, Diablo II’s online ladder seasons remained active for over two decades, with Blizzard supporting the game until even after Diablo III launched — a testament to its staying power.
Diablo II arguably has the most hardcore long-term fanbase of the five. Even after the release of Diablo III, many fans stayed loyal to D2 for its dark tone, deep loot system, and complex builds. The game’s modding scene is vibrant, with mods like “Median XL” adding new life and content. Blizzard’s release of Diablo II: Resurrected in 2021 gave the fanbase a modern, remastered version that brought in both returning players and newcomers, proving its legendary longevity.
“Stay awhile and listen.” – Deckard Cain, the wise and weary lorekeeper, often quoted (and lovingly parodied) by fans.
4. Star Wars: Knights of the Old Republic (2003)
Developer: BioWare
KOTOR is often hailed as one of the best Star Wars stories ever told, game or otherwise. Developed by BioWare at their creative peak, it masterfully blended traditional Dungeons & Dragons-style mechanics with a fully voiced cinematic experience set in the Star Wars universe. The game gave players meaningful choices, complex companions, and one of gaming’s most legendary plot twists. With a well-crafted morality system, rich lore, and powerful role-playing depth, it offered a rare combination of fan service and narrative sophistication.
HK-47 became so popular that he appeared in other Star Wars media, including The Old Republic MMO and reference books — a rare feat for a video game-exclusive character.
KOTOR has one of the most enduring fanbases in RPG history. The game’s story, character development, and moral choice system are frequently cited as benchmarks for narrative design. It remains a go-to Star Wars experience for many fans, with a massive modding community that continues to update textures, add content, and even create new storylines. The announcement of a remake (currently on indefinite hold) has only rekindled interest and nostalgia in the original.
“Statement: I will honor our agreement by slaughtering anything you point me towards, master.” – HK-47, the fan-favorite assassin droid known for his love of violence and disdain for “meatbags.”
3. The Witcher (2007)
Developer: CD Projekt Red
The Witcher stood out by embracing adult storytelling in a world that was morally gray and deeply human. Rather than clear-cut heroes and villains, choices in the game had complex consequences, often only becoming clear much later. Its gritty atmosphere, heavy use of Slavic folklore, and unique protagonist (Geralt of Rivia) gave it a tone that was very different from typical Western or Japanese RPGs. The combat and UI were rough, but the writing, world-building, and ambition made it something special — and the beginning of a genre-defining trilogy.
The English localization of The Witcher was heavily censored and awkwardly translated at launch, which fans later fixed through unofficial “restoration” mods to preserve the original tone and dialogue.
Although its popularity was eclipsed by The Witcher 3, the original Witcher retains a dedicated fanbase that appreciates its mature storytelling, atmospheric world, and unusual combat system. Fans revisit it as the foundation of Geralt’s journey, and CD Projekt Red’s consistent updates and the “Enhanced Edition” release helped preserve its appeal. Community mods that improve visuals, fix bugs, and rebalance gameplay keep it playable today, especially for lore-completionists.
“People like to invent monsters and monstrosities.” – Geralt, reflecting on human nature and prejudice, a recurring theme in the series.
2. Fallout 3 (2008)
Developer: Bethesda Game Studios
Fallout 3 reinvented a beloved isometric RPG series by transitioning it into a fully 3D, first-person open world — and pulled it off with ambition and style. It combined the retro-futuristic aesthetic and bleak post-apocalyptic setting with immersive storytelling, a huge world to explore, and choice-driven gameplay. The V.A.T.S. combat system allowed for tactical shooting, and the karma system added weight to decisions. Its mix of atmospheric exploration, dark humor, and moral ambiguity gave it a distinctive identity and set a new bar for RPGs in a modern setting.
If you kill the radio DJ Three Dog, his broadcasts stop — permanently. Fallout 3 was one of the first big RPGs to let you alter your world so drastically through choice.
While Fallout: New Vegas has arguably surpassed Fallout 3 in cult status, Fallout 3 still has a strong, loyal fanbase. Its shift to first-person, open-world RPG design introduced a new generation to the Fallout universe. Fans continue to mod the game heavily, fixing bugs, updating visuals, and integrating modern features. Its place in the Bethesda-style sandbox RPG lineage keeps it relevant among series veterans and modders.
“War. War never changes.” – The iconic phrase that opens the game (narrated by Ron Perlman), continuing a tradition from the original Fallout games.
1. The Elder Scrolls IV: Oblivion (2006)
Developer: Bethesda Game Studios
Oblivion was revolutionary for its time, offering an unprecedented sense of freedom in a fully open world where nearly every NPC had a daily schedule, and you could go anywhere, join multiple factions, or completely ignore the main story. The game’s radiant AI and lush, sprawling environments made the world feel alive. Coupled with voice-acted dialogue, deep lore, and endless side quests, it delivered a classic high-fantasy sandbox that set the template for future open-world RPGs. It was also incredibly mod-friendly, helping extend its life and influence.
Oblivion features one of the earliest widespread uses of procedural dialogue systems in a major RPG — but all 1,000+ NPCs were voiced by just a handful of actors, leading to hilarious repetition (and instant meme status).
Oblivion’s fanbase has remained active for nearly two decades, largely thanks to its extensive modding scene. Even after the release of Skyrim in 2011, many fans continued to play and mod Oblivion, appreciating its more classic RPG feel, unique quest designs (like “The Dark Brotherhood”), and the nostalgic charm of its vibrant, alien-like world. Mods like “Oblivion Reloaded” and full overhauls such as “Oscuro’s Oblivion Overhaul” and “Better Cities” keep the game alive today.
