Looking at the calendar in the upper-left corner of my blog, I see that it has been over two months since I had last written anything in this blog. that is partially because of my busy summer, in which I spent more time traveling than being home.
Meanwhile, Blizzard's fourth BlizzCast was released a few weeks ago, and it had much to discuss on the StarCraft 2 universe and how the technicalities of the game were shaping up.
Minerals and mineral gathering have changed dramatically from StarCraft to StarCraft 2. The amount of minerals gathered in a single trip has been reduced from 8 to 6. Although I was at first critical of this, the reduction is compensated by the new and improved worker movement AI. This improved AI allows more efficiency in worker movement: workers no longer move from left to right looking for a mineral spot to gather from, but know what spots will be available even before another worker may be finished gathering his own load. Another new feature is the ability to automatically put workers to the mineral fields by setting the rally point on top of one of the fields. Although these new features take away some of the micro of the original StarCraft, they make it easier for new users to get the best experience out of StarCraft 2.
Another issue discussed in the BlizzCast was mind control and other infestation procedures. No unit yet has followed in the path of the Dark Archon, being able to permanently capture a unit, but the Corruptor, a new Zerg unit, has the ability to temporarily take control of a unit and turn it against its allies. Developers realized after the release of StarCraft: Brood War that the Dark Archon's ability to permanently mind control another unit was two-fold - it took away one unit from the enemy, generally a very powerful unit, and added a unit to the player.
In the same way, infestation is limited in the amount of time it takes over buildings. The advantage goes to the Zerg, however, because when the Infestor takes control of a Barracks, Infested Marines instantly pop out and attack any nearby enemies. Also, the Zerg can use these units many, many times, instead of the instant and deadly barrage of the Infested Terrans of StarCraft.
These new dynamics are an interesting twist in the StarCraft universe, and will help to make StarCraft 2 more diverse and complicated than it's predecessor.
And that is my take.
