How is the full version planned to differ from the Early Access version?
“Leading up to release you can expect a plethora of incremental improvements and new features to be added to the game, as well as the inclusion of new classes and races. The 1.0 release will include the full game including Acts 2 and 3.”
What is the current state of the Early Access version?
“The Early Access version of Baldur’s Gate 3 includes Act 1 of the game which, in one playthrough, is approximately 25 hours of self-contained content. 6 player classes are supported and 9 races/subraces with more to be added later. There are 5 origin characters which you can recruit (but not play as for now). Most of Baldur’s Gate 3’s advertised features are included though some are still work in progress. Not every language is currently supported, as our writers are still developing the game which makes translation difficult.
We’ve worked hard to release an Early Access version that feels complete, fun to play, and has as little stub (unfinished) content as possible. There are bugs and there will be changes to content (often based on player feedback), but our goal is to already now give you something that’s genuinely fun to play.”
