E3 2018: Every Missing Video Game
6. Metroid Prime 4
Though announced at E3 2017, Metroid Prime 4 was nowhere to be seen at Nintendo's E3 conference, which seemed to turn into the Super Smash Bros. hour pretty quickly.
Nintendo said that they weren't ready to show off more of the title, which is more than fair, given the other things they had to show at their conference. That said, the lack of further info wasn't helped by the fact that another fan favourite series, Animal Crossing, went AWOL at the event too.
The last decade has been a somewhat frustrating one for fans of Samus Aran, who's been absent from consoles ever since the last entry in the Prime series in 2007. It's a long time to wait for a follow-up, but with knowledge that the game is still being made, surely another year of waiting isn't too much to ask?
