Possibly the most deserving game of attention on this list, Prey just didn't do as well as it deserved. Whatever the reason may be, it certainly deserved better.
Ever since its reveal at E3 2016, Prey looked fantastic. A horror title with the creativity and freedom of the Dishonored titles taking notes from BioShock looked to be exactly what gamers were needing. Despite having fantastic critical reception, Prey failed to make any big impact in its sales and unfortunately hasn't got the attention it truly deserved.
Prey entered the charts and failed to make much ground against games like Mario Kart 8: Deluxe, which was a simple re-release of a Wii U title. Despite that, Prey still garnered fantastic praise from critics and gamers alike, earning it a nomination for 'Best Action Game' at The Game Awards 2017.
It's such a shame that Prey flopped like it did. Hopefully Bethesda can push some more attention onto the game in 2018 so that more people can see what they missed.
