I’d also comment on Broodwars approach of balance by making everything overpowered (in the right circumstance) rather than nerfing anything that stood out at any point.

There were a lot of units that could single handedly turn the tide in the right scenario. Vulture mines could stop a rush in their tracks, storm could wipe an army, dark swarm could negate a dug in fortification, a reaver in a shuttle could take out all production.

It led to crazy chaos and it was an incredibly entertaining spectacle.
