Another problem to consider in today's age is the audience.

People either only buy titles they know (there's a staggering amount of people who admit to only ever owning Fifa, GTA & Call of Duty games), and they only get interested in new IPs that get bucket loads of coverage, such as Overwatch (unless they completely break the rules and are a stroke of creative brilliance, like Minecraft). Even Battlefield had to wait years and years to get to where it is today. Titanfall 2 for example blew COD out the water completely, in every single way, but it's sales were a complete disaster for the simple reason it didn't have the words 'Call of Duty' in it's title. Racing games in general are also not overly successful any more, in fact they're barely ever made! People can get their speed fix from games like GTA now, and create their own track in the process.

'Pick up and play' is so much more popular than 'steep learning curves, difficult to master'. People want to play games with their friends, not make new ones, and all their friends will unfortunately not be on Wipeout. People also like Clans, eSports, customisation, and character creation, and Wipeout has none of those things.

Despite all that negativity there is certainly a hole in this genre, and Omega has proved that Wipeout is still easily good enough to fill that hole. They just need to make something new, that's truly brilliant, and shove it in everyone's faces long enough that they all go buy it.
