I nominated ESO for the "Haunts My Dreams" award, "because this game doesn’t just haunt your dreams. It consumes your thoughts every waking moment of the day. This game doesn’t demand your time. You give it willingly."
Which category would you nominate ESO for?To nominate ESO for an award: go into the Steam application, find the page for "The Elder Scrolls Online: Tamriel Unlimited" in the store, and the purple banner just below the videos will say "Nominate this game for The Steam Awards." Click the button, and choose a category.
Best,
Ettin
