10 Video Games Supposed To Release On Other Consoles
4. Halo: Combat Evolved
Though it's tough to imagine Halo: Combat Evolved as anything other than the seminal Xbox launch title that it absolutely was - without which the Xbox brand wouldn't be what it is today - that wasn't the original plan at all.
A small team at Bungie began developing Halo as a real-time strategy game in 1997, with plans to release it for PC.
By 1998, it had become a third-person shooter, and industry hype for the game began to build after Steve Jobs agreed to premiere the first footage at the 1999 Macworld Conference & Expo.
But by 1999 Bungie was in dire financial straits after spending $800,000 to recall defective copies of their previous game Myth II: Soulblighter, prompting Bungie to broker a deal with Microsoft, at which point the game was repackaged as a flagship Xbox-exclusive launch title.
At this point, gameplay was changed from third-person to first-person, and major features such as a planned open-world and a more expansive campaign were scrapped in a mad dash to meet the Xbox's November 2001 release date.
Despite being such a frantic sprint to the finish line for Bungie, the end result was universally acclaimed by critics, and of course kick-started an immensely popular FPS franchise.
Frustratingly for PC players, though, they had to wait almost two years before the game finally hit Windows, while poor Mac owners had to wait a few extra agonising months on top of that.
