well, i played it for about 2.5 hours yesterday.
it is alot better.
you dont even participate in the battles (you could only ever hit like 5 damage in the first one, that sucked...)
you control one of your spectrobes, and the other one even has exceptional ai.
whole incubation process is way easier to understand.
it is alot easier to figure out what you need to do for a particular mission.
you can dig up these little wonder ball type things that have like 6 minerals inside them =)
if you didnt like the first one, because it was way too tedious, you should give this one a try.
