The full version of Original Sin 2 will include more difficulty modes, added content, new skill schools and a new playable race, the Undead. In its current state there are some features missing and most of the single-player campaign is not yet available.
While Divinity: Original Sin 2 is in early access the full game is expected to be released later in 2017. Act 1 has already been released and includes about 8 to 10 hours of gameplay.
