Compare Knights of the Sky Key prices across trusted key stores and find the best deal. Developed by MicroProse Software, Inc. Published by Retroism, Nightdive Studios. Released on 4/1/2015. Available on PC. Genres: Action, Simulation.

A WWI dogfighting sim from MicroProse that puts you in the cockpit hunting real aces like the Red Baron. Old bones, genuine tension, if you can stomach the age.

Knights of the Sky is a World War I aerial combat simulation originally built by MicroProse, now republished for modern platforms. You fly biplanes and triplanes across the Western Front, managing campaigns in which your core objective is tracking down and defeating 16 historically significant German aces, including Manfred von Richthofen himself. Intelligence reports and in-game news dispatches guide your hunt, giving the campaign a cat-and-mouse quality that most arcade flight games never attempt. The design philosophy is closer to a career sim than a pure action game: every mission carries stakes because your pilot is mortal, replaceable, and tied to a running tally of kills and reputation. From a decision-depth standpoint, the game rewards patience. You choose when to engage, when to disengage, and whether to chase a wounded enemy into unfriendly airspace. Fuel, altitude, and sun position are all factors, and the AI opponents, while dated by modern standards, vary their aggression depending on who you are facing. Named aces fly more aggressively and use period-accurate tactics, which gives those encounters a different weight than routine patrol interceptions. It is nowhere near the fidelity of something like IL-2 Sturmovik, but the underlying systems still hold a logic that rewards players who bother to learn them. Here is the honest problem: this is a 1990s game sold largely unmodified. The interface is a museum exhibit. Control customisation is minimal, documentation is sparse in-app, and there is no tutorial that would satisfy anyone who learned gaming after 2005. The Steam review pool is small and mixed at 53 percent positive, which tracks with the reality that most buyers either have nostalgia for the original or bought it expecting something more polished. The mod ecosystem is essentially nonexistent on the current release, which is a real gap for a game that could genuinely benefit from community patches. For newcomers: approach this like you would a DOS-era strategy title. Find a fan guide, read the original MicroProse manual if you can locate it online, and accept that the first few missions will feel opaque. Once the campaign logic clicks, particularly the ace-hunting structure, there is a surprisingly focused experience underneath the rough exterior. The satisfaction of cross-referencing intelligence reports to time an intercept with a named pilot is something more modern flight games rarely replicate. If you have a strong interest in WWI aviation history or grew up with MicroProse titles, the underlying design still justifies a look. If you want a polished modern flight sim with handholding, functional UI, and active multiplayer, this is not where you should be spending your time. It is a preserved piece of PC gaming history, and it should be evaluated on exactly those terms. Diego, Scout Team

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
