It doesn't matter how good your hardware is, consoles live or die by the quality of their games, and the Xbox's rise has been peppered with some of the most iconic games of all time.
From world wars to interplanetary skirmishes, from football pitches to the fictional streets of San Andreas, the Xbox has introduced us to familiar places and brave new worlds.
With the Xbox One arriving, we've brought together the most important games in the history of the Xbox brand, picking out the obvious tent pole titles and some of the more obscure but vital games as well.
Oddworld: Munch's Oddyssey
Every games console has to start somewhere, and although the most iconic of the original Xbox games characters would be Master Chief, it was a Gabbit called Munch that holds the distinction of being the first character to be seen being played on an Xbox in public.
Seamus Blackley showed off Munch's Oddyssey at the Consumer Electronics Show in Las Vegas in January of 2001, and although it will never be remembered as a classic, it has rightfully earned its place in the annals of gaming history.
The Halo series
For Nintendo it's Mario, for Sega it's Sonic, and for Xbox the most important character is without doubt Master Chief, the main protagonist of the Halo series - a gaming leviathan that has done more than any other single title to make the Xbox a gaming great.
The trailblazing Halo: Combat Evolved sold in droves exclusively on Xbox. Then came Halo 2, which went a long way to establishing the Xbox as the home of connected gaming and making Xbox Live the powerhouse that it has become.
Next up was Halo 3, which smashed sales records and moved through to Halo 4 and Halo: Spartan Assault. Indeed, the battle between the UNSC and various alien races will always be intrinsically linked with the Xbox.
Grand Theft Auto
No list of gaming greats over the past 15 years would be complete without a section detailing the Grand Theft Auto series from RockStar. Among the most critically acclaimed games to ever arrive on the Xbox and Xbox 360, they are also the most popular, smashing sales records and gathering more fans in the process than One Direction and Justin Bieber put together.
Grand Theft Auto 3 changed the gaming landscape with its sandbox world, whilst GTA IV took the last generation to a new high and the latest release - GTA V - will be remembered as the finest of swansongs for the Xbox 360.
The adventures of Commander Shepherd are yet more examples of how intelligent storytelling and action thrills can take gaming to a new level. Mass Effect blended combat, team building and exploration with the odd (controversial) sex scene and glorious graphics.
With sequels garnering critical acclaim and the Bioware game now firmly established as one of the most important gaming IPs, we can't wait to see what Mass Effect 4 brings in this next-gen world.
The Orange Box
Games from Valve are always big events in gaming, but the Orange Box gave us not one but three new titles as well as including the back catalogue of Half-Life games to boot.
There simply wasn't a weak link in this collection of immediate classics – Half-Life 2: Episode 2 was stunning, Team Fortress 2 brought brilliant multiplayer quirkiness and Portal was so inspirationally brilliant it created a thousand cake and companion cube memes. Still Alive.
Gears of War
Arriving early in the life of the Xbox 360, Gears of War proved to be a smash hit for the Xbox, bringing the battle of a rag tag bunch of obscenely muscled guys and gals against the monstrous Locust aliens.
Based on third-person cover and combat, the game garnered plenty of critical acclaim and showed off the Xbox's graphical prowess as it chainsaw bayoneted its way through the hordes of Locust. And then there's the lovingly rendered rippling muscles. Lots and lots of rippling muscles.
Call of Duty
Starting life as a WW2 first person shooter, the Call of Duty games steadily evolved into the most familiar, popular and profitable of franchises as it moved from World War 2 into Modern Warfare.
The games single player mode was effective and popular but it really came into its own on the Xbox as a multiplayer experience. Like the also popular Battlefield and PC classic Counter Strike, first person shooters proved to be the perfect form for multiplayer action and the Xbox Live experience boosted longevity.
Racing games have been popular since the coin-op days, and every console worth its salt needs to show its quality on the asphalt. Competing with the brilliant likes of Project Gotham Racing, Microsoft's Forza is perhaps the racing title that is most intrinsically linked with the Xbox.
Beautifully modelled cars, finely tuned racing and some really nice social elements have made Forza a big part of the Xbox story, and the wheel keeps turning as Forza 5 rolls up to the Xbox One start line.
Peter Molyneux is a gaming icon and his time at Lionhead brought a classic fantasy series in Fable. Molyneux's typical brilliant ideas, some of which proved to be a bit "out there", proliferated and the titles remain a firm favourite.
Plus there's something very right about your deliberately evil character getting more and more devilish looking.
Don't underestimate the power of peripheral-based music games in the Xbox story. Rock Band and Guitar Hero were prime examples of how console gaming didn't all need to be about cars, guns and platforms.
Rhythm games have become a real fixture in console gaming, but bringing a guitar controller to the mix was a stroke of genius as the Xbox proved to millions that it wasn't just joypads that could make local multiplayer exciting.
It's risky creating a new IP - expensive and without any guarantee of success, and yet Ubisoft's creation of the Assassin's Creed titles has paid enormous dividends, and the Xbox has been a big beneficiary of that.
Huge playable maps that just beg to be parkoured around, breathless kills and the first amazing swan dive from a tall tower all stood out through the series and its history-jumping storyline.
The brilliant original BioShock was not without its flaws, but it did something that very few games ever carry off - providing genuine narrative twists and turns that got gamers talking. As well as *that* scene with a golf club and the genuinely creepy storyline, this underwater world was one of the most detailed and thrilling gaming worlds ever designed, and the recent successor BioShock Infinite built on those foundations.
These games proved beyond doubt that the Xbox was capable of providing gritty, mature gaming gems with heart and soul, and that a strong story was vital in creating a truly engrossing environment.
Football is big business and EA SPORTS now legendary series has become the go to title for those wanting to see what happens when you plonk Lionel Messi in the same team as Cristiano Ronaldo or whether you are so much better than your online opponent that you can score with your goalkeeper.
With a new version every year the series has been in constant evolution, and the next gen promises to give us another big hoik towards making Wayne Rooney look perfectly like Wayne Rooney
Not one for the hard core gamers, but quite possible a title that proved to those more casual players who snapped up the Kinect for Xbox 360 that motion control was the future.
The Kinect, of course, tracks your movement, and when that movement is to the music then you might just find that the rhythm is, as they say, going to get you.
MMOs are all very well, but for many people the chance to participate in a role playing game redolent with dragons and swords and sorcery without having to deal with all those, well let's be honest, annoying other real people is hugely attractive.
The Elder Scrolls series brought us massive worlds, massive monsters and massive levels of brilliant gameplay. Did we mention the dragons?
