That is actually very offputting. Zeratul had a really active role in SC1 and it seems he just became another old wiseman. Also why would he be in such a hurry? Etc. etc.

It also seems the zerg aren't the big baddy thing, which is even more retarded.

First of all, this is basically the terran campaign - zeratul likely has a larger role in the protoss campaign. Second, absolutely nothing suggests that he's just an "old wiseman." infact I've heard of some really action packed single player sequences starring him.

As for the zerg not being the big baddy - why is that retarded? The zerg being overshadowed by the Xel'Naga as a threat seems pretty thrilling - and their return has been foreshadowed from the very beginning.

Not true, Citadel for blink and especially charge can really be a game winner in the midgame, i almost always build it first

See, the Xel'Naga have every right to annihilate the Zerg. However, the Xel'Naga were never people who killed, in fact quite the opposite, they created races. Making the Xel'Naga off as bad for the protoss or terran is absolutely retarded. The Zerg are the only ones that want to absorb and store all life's genetic data.

Also, the Protoss campaign is 2 years away, probably more, so as far as SC2 is concerned, he's the old wise man.

For what purpose did the Xel'Naga create races? I mean, if you look at most science fiction, most created races are used for either slave labor, or as cannon fodder in wars... Yes the Xel'Naga created races, but I don't think we're ever told what their motives were. We do know that for whatever the reason, the protoss rose up and drove them off their homeworld.

And even though the protoss campaign is a ways away, did you ever watch the VERY first preview cinamatic for SC2? it was zeratul hacking his way through tons of zerg, and being confronted by kerigan. And there are missions related to this in the terran campaign. So don't worry about him being relegated down to just an "old wise man". (Though he won't be the star, but he never was)

Oh god please no lore discusion... I believe that Blizzard writers can do the best for the story themselves, rather than profi consultation on net forums...

There is more unknown than know about the Xel'Naga. They do not appear to like to kill, but they have interfered with races on a massive scale. The Xel'Naga are directly responsible for the massive civil war that killed millions, if not billions, of Protoss. They didn't exactly learn a lesson from that one either as they went to create the Zerg as the second half of their experiment. The Zerg then proceeded to kick the crap out of the Xel'Naga which could leave a race a touch upset.

Xel'Naga's reckless experimentation is also an issue here. The whole threat could come from another round of playing god with a races genetic make-up. As you might recall, the Zerg and Protoss each represent one half of what they want so far. Consequently, the two need to come together someone. Create an enemy to unite against and the Zerg will eventually try to absorb the Protoss into the collective. This creates the next generation, and continues the lineage through their normal means. Given that the Zerg have had the most military success against the Xel'Naga it is only natural that everyone turn to them.

Metzen has screwed up on lore a couple times in the past so he might want to listen to a few of the lore nerds that run rampant. Regardless, this is just speculation about possible explanations for the story mode. Since it currently involves all of three people, I kindly invite you to just skip our posts. Hell I will even make it easy for you for me. I'll put a lore warning at the start as an act of kindness.

Damn, you aren't making the wait for StarCraft II any easier. My hype level just went through the roof.

Lore Ahead

Last time I went through the lore this question seemed to be answered. Given this involves some use of Wikis, but I trust hardcore internet nerds to filter their own nerdiness. Xel'Naga, as a race, are dying. This is apparently a cycle that happens every so often in the universe. In order to continue on their line they needed a species that had purity of essence, and one that had purity of form. The Zerg represent the former, and Protoss the latter. This means one very, very exciting turn of events though. We will see a Zerg/Protoss hybrid during the campaign at some point.
