In D20, every fight is cinematic. If you give them the same feel in your game and have an end goal separate from killing monsters, a huge 3d environment and a ticking clock of tension then you’re emulating it perfectly.

DA2 takes a different take for me when I realized that you're playing through Varric's retelling of the story. It kinda explains why people are falling out of the sky to join the battle and other inconsistencies.
