10 Ways Your Favourite Video Games Were Almost Radically Different

After shipping Doom 3, Id Software began working on a sequel that was going to take the franchise back to a place it hadn't been in years: Earth.

Following in the footsteps of Call of Duty, the original idea for the game was a similarly-inspired modern military shooter that swapped terrorists out for demons.

But while the enemies were different, design philosophies were the same. Dropping both the survival horror elements of Doom 3 and the fast-paced gameplay of the original titles, the then-titled Doom 4 was much more sluggish and slow-paced than any of its predecessors.

Featuring the same point-and-click style shooting as CoD, the game would have had you fighting as part of a team of soldiers pushing back against the demonic threat that had invaded Earth over huge action set-pieces.

Knowing that the series had strayed too far from its roots however, the team eventually scrapped this idea completely after trying and failing to make it work for years. It was for the best however, because what they came up with in its place was one of the greatest first-person shooters in years.
