Sheesh, that’s a lot to look at, so let’s roll initiative and dive in.
It’s very good!

More origin stories will be available in the full release.

That places it in the quintessential Forgotten Realms D&D setting, along the Sword Coast.
Avernus is set in 1493, just one year before Baldur’s Gate 3 picks up.
Baldur’s Gate 3 gameplay
Baldur’s Gate 3 is a vast RPG with turn-based combat.

Fortunately, you could check out videos of gameplay on the interwebs to see it for yourself.
Outside of combat, you’re no longer restricted to turn-based actions.
This is, after all, Dungeons and Dragons.

Yes, put that weighty Player’s Handbook down, you’re going to break a toe.
Baldur’s Gate 3 splits skill tests into active and passive checks.
Passive checks occur when the game checks something without a visible roll.

If you do, cool, secret door!
If not, you go on as if nothing happened.
The outcome of passive checks depends on your overall stats, rather than the luck of the dice.

Is Baldur’s Gate 3 multiplayer?
Baldur’s Gate 3 is multiplayer with up to four players in the same party.
you could each follow your own quests, or work together to overwhelm your enemies as a group.

Of course, you’re free to also split up while working towards the same objective.
Have a couple of players distract some guards, while another sneaks in to grab some loot.
Oh, and someone else is probably setting stuff on fire in the corner.

That’s classic D&D, right there.
How big is Baldur’s Gate 3?
Act 1 will last for roughly 20-30 hours, depending on how much you explore while playing.

However, that’s just with one character.
If you want to try every class, that’s already hundreds of hours.
As Matthew puts it, “the meat of your mulling wont be answered for some time”.
