I have been enjoying the Warhammer Quest iOS game. I never played the board game. (I’ve never played the miniatures game either. I did play a fair amount of Fantasy Roleplay first edition.) It has an unusual “action economy”.
During a single turn (that would be a round in D&D), a character can take their full movement, make their full set of melee attacks, make their full set of missile attacks, use all their special abilities, use all items they have readied, and cast spells until they run out of spell points. About the only restriction is that once they make an attack, they can no longer move until the next turn.
Contrast that against Conclave where you get one-and-only-one minor action and one-and-only-one major action each round. Although characters will often have abilities that combine, e.g., movement and and attack into one action.
In practice, this seems to work fine in Warhammer Quest. To me, it begins to feel more like a one minute combat round than AD&D ever did.
