Blizzard’s StarCraft II patch to v2.1 released earlier this week introduces certain free-to-play features (map editor, Arcade access, access to additional races, etc.) but also two nice tips of the hat to SC1/Brood War players:
1: Big Game Hunters is finally back, and official! (Click here & scroll down a bit.)
2: An HD remaster of the original StarCraft soundtrack has been added to the Options–>Sounds menu.
Let the good (old) times roll!
Also: Amazing the difference the soundtrack makes to the StarCraft 1 remake, StarCraft Mass Recall. Still an open question as of this post as to whether or not it works for free-to-play players, but I’d bet it works.
