BioWare claims Dragon Age: The Veilguard has 140,000 lines of dialogue, which is probably more than Baldur's Gate 3, but definitely less than Starfield
There are a bunch of reasons why there's been a ten year wait for a new Dragon Age. Developer BioWare has been busy with other projects during that decade, and big-budget games generally take longer to make now than they did back in 2014. But according to the game's creative director John Epler and creative performance director Ashley Barlow, there's a much more straightforward reason: game big.
