Q: How did you go about replicating all the unexpected “bugs” that made BW micro
    so special? Did you simply reuse code from the original game, or did you find a
    solution to replicate the nuances of BW’s gameplay?

    A: StarCraft: Remastered is able to achieve this effect as it uses all the same
    gameplay code as Brood War. This means that Dragoons and Goliaths are still a
    bit derpy in how they react to movement commands. The Reaver’s shot doesn’t
    always find a target. Mutas stack.

    The fact is that the gameplay is identical enough that old replays from 1.16
    will play and work just fine under StarCraft: Remastered.
