Baldur's Gate 3 devs didn't want to include a core D&D rule in their RPG, but players proved them wrong: "We were afraid it was going to slow down the gameplay too much"

Baldur's Gate 3.

Baldur's Gate 3 almost left out a core piece of the D&D ruleset that was only saved thanks to the RPG's early access community.

In D&D, Reactions are a tool that allows players to respond to certain triggers, even when it's not their turn. Perhaps the most famous is Counterspell (which is prompted when a creature casts a spell, and can automatically stop that spell from casting), but there are dozens of other Reactions for all sorts of different situations. If it had been up to Larian, however, they might not have been in the game at all.
