Huh, that's an interesting bit of trivia I didn't know. Apparently, their first ever game was a point and click horror title called 'Zombi', which ZombiU is loosely based off of (and presumably in the same franchise as). It's technically an older franchise than Resident Evil or Silent Hill (or even Alone in the Dark).
So yeah, pretty interesting isn't it? Kind of goes to show how little people know about the history of our 'favourite' companies now!
