SCVs can patrol, so if you activate auto-casting of the SCV's repair ability, that SCV will repair damaged buildings or units it encounters while on patrol. The SCV will repair nearby units and buildings and continue its designated patrol pattern again after the repairs are complete.


4. What use does the Overlord usually see versus the Nydus Worm? That is, in what capacity is each transport mechanic used?

It all depends on a player's choice in each case. When you want try out a sneaky and clever attack on the enemy's base, the nydus worm can be useful in that role as a more tactical and general choice for harassing the enemy's economy. However, you can also use a mass overlord drop just like the original StarCraft, for an aggressive, all-out attack. However, the overlord drop is riskier, as you're putting much of your supply and the cargo in jeopardy if you encounter strong anti-air defense.

7. How has more efficient AI and pathfinding affected the game? Does it make the game easier?

AI in StarCraft II is much more developed from the original StarCraft. For example, the computer is required to scout to find you now in every difficulty mode. In higher difficulty modes, the AI will adapt to what it sees you are building to counter your selected strategy with key units of their own. This means that the computer no longer cheats as far as "knowing" where you are and what you're doing. It can only react to what it sees when their scouts find your units and bases.

The pathfinding is also much improved in StarCraft II, which will reduce some frustration when directing your units to move long distances around varying terrain. Certain melee units are also smarter about attempting to surround enemies, but we don't believe this makes the game "easier." Players who choose to micro their armies will still have an advantage.
