Strategy games are one of the oldest genres, with hit titles that go all the way back to the 90s, but they became a powerhouse of PC gaming in the 2000s and beyond. Nearly every year, at the start of the 21st Century, it featured some sort of strategy game on its best games of the year lists, and many massive franchises had their first game or a popular sequel release.

Steam: 10 RTS Demos You Should Try Before Buying The Full Game

RTS titles often vary wildly in terms of style, mechanics, and complexity, and sometimes it's best if players try out a demo before making a purchase.

Many of the best strategy games from the 2000s are still a blast to play today, with a handful of them still receiving DLC or updates on Steam despite being well over a decade or two old at this point. Even the best old strategy games that haven't stood tall in the test of time, are still beloved for the impact that they have had in the genre, and for paving the way forward to inspire hundreds of amazing strategy games ever since.

10 2000 – Europa Universalis

Metascore: 87

The first installment in the long-running grand strategy series. Originally based on a French board game from the 90s, Europa Universalis puts players on a two-dimensional map of Europe, where they will control a nation across multiple scenarios spanning from 1492 to 1801. The game features a real-time clock system that has the years fly by, forcing players to make decisions semi-quickly. It was also one of the first to include resource allocation on a global scale. If a player doesn't carefully spend their nation's money, the other nations will advance past them and pose a competitive or combative threat.

The game was a massive hit and has sequels that are still wildly popular today including 2013's Europa Universalis 4 which features more updated systems of the original. Whilst the first in the series isn't accessible for being trapped on inferior devices, Europa Universalis 4 sits as a best seller for strategy games on Steam, with its developers, Paradox Interactive, creating even more amazing titles like Crusader Kings and Stellaris.

9 2001 – Sid Meier's Civilization 3

Metascore: 90

By 2001 the Civilization series was already on its third main entry. This grand strategy series has reinvented itself over and over. The reception to Civilization 3 was great, and it propelled the franchise to even greater heights than it already was, allowing for the franchise to flourish, with fans waiting eagerly for the next installment, albeit with patience.

The reason that fans adored Civilization 3 was due to the convoluted mechanics that make the game harder for new players. Players must build a kingdom from the ground up in 4,000 BC and bring it all the way to the modern age. The time frame and pure scale of the game was larger than anything before it. It's a classic for those who remember it, and a true challenge for all, with strategy and politics abound.

8 2002 – Warcraft 3: Reign of Chaos

Metascore: 92

Before players knew the world of Azeroth through the hit MMO World of Warcraft or the CCG Hearthstone, they knew the fictional universe full of Orcs, Elves, and other fantasy creatures from the RTS games in the Warcraft series. This classic refined the systems that would go on to be in nearly every RTS. Simultaneously building, defending, and attacking with a large variety of troops was the core of the game, and was far ahead of nearly every other strategy game that year.

It won multiple game of year awards and felt like a new fresh take on the RTS genre that would have ripple effects for quite a while. Players command a squad of soldiers, making tactical choices as fast as possible while utilizing every piece of the environment.

The intense presentation and gritty combat was clearly the bolt of electricity RTS fans of the era wanted, The ripples are still being felt today, as the game has had two sequels and a remaster, and all three titles are still receiving updates and DLC as recently as 2023.

The game was considered the best of its year in strong part due to the fact that it was considered by many to be the first fully successful console RTS. It was instantly a new classic that still received support and had a consistent player-base until the sequel finally came out in 2016.
