John Romero is about a influential as they come in the sphere of first-person shooters, having had a hand in the most important of them all, Doom.
In a recent interview with Develop, Romero offered his thoughts on the possibilities still available to designers working within the shooter space.
"There are unbelievable amounts of new stuff to do in that genre," he said, before going on to describe something that sounds remarkably like Destiny, which launched today.
"Take something like World of Warcraft - what if that was a shooter? You have a giant world full of quests, and tons of people with PvP already in the game. If World of Warcraft was a shooter, that would be brand new - nobody would have seen something that big and that cool.
"And it wouldn't be anything like WoW because of the nature of being a shooter - it would probably concentrate on a lot of areas that were similar to Team Fortress 2. Perhaps villages would become like TF2 levels, where you would try to score as much as you could before deciding to move on. Or that area would have specific goals, like taking out five snipers and two demo guys to retrieve some key items. Perhaps once you've exhausted that village, you could go to another one down the road. And maybe the planet's full of them - nobody's played a game like that."
Romero, who recently confirmed that he's currently working on a new shooter, wrapped up by saying: "Shooters have so many places to go, but people just copy the same thing over and over because they're afraid to try something new. We've barely scratched the surface."
