There will be a required ~15GB day-one patch for The Elder Scrolls Online: Tamriel Unlimited on PS4 and Xbox One.
The revelation was tucked at the bottom of a FAQ accompanying yesterday's Elder Scrolls Online beta-invites news.
The reason for the ~15GB patch: the game is bigger than a Blu-ray disc's 50GB capacity.
"ESOTU is an incredibly massive game, both in terms of sheer scope and the data required to bring you this truly enormous experience. At the moment, the client will exceed a 50GB Blu-ray disc which means there will also be a large day-one patch that is somewhere in the region of 15GB," explained Bethesda.
There haven't been any games on PS4 or Xbox One that come on or successfully use multiple discs. Yes there's a cost associated with cutting another disc, but maybe there's more to it than that.
We had an almost identical scenario with Halo: The Master Chief Collection on Xbox One, which had a 15GB day-one patch and for the same reasons. Back then Microsoft said it "wasn't feasible" to offer the game on two discs, suggesting it couldn't rather than it wouldn't.
