But each campaign is going to be the same length as all three campaigns from the first game combined. So that's not really a good comparison.
You mean... like in an expansion?
Another "fully featured campaign" for a main game you already bought.... that is what people usually call an "expansion" and they don't sell them at full price. "They" being other companies than Blizzard lol.
Even if these 3 campaigns really are "gods gift to gamers" (i'm saving my real laughs for after release just in case), then they are still overcharging for them. Period. 3 fully featured campaigns != 3 games.
A company interested in offering a fair deal might have sold the first game at full price and offered any other "campaigns" you want to buy at expansion/half price. Several companies propably would simply have stated that their game will be "much more extensive than any other" and not charged anything extra at all. Blizzard however is sick with their success of World of Warcraft. It's been said before: They could likely sell crap in a can and people would still buy it. This... just shows that Blizzard "heard" of that notion too. They appear to be pretty much convinced people will by *anything* they make and that is why they are milking as hard as they think they can.
Not rocket science. Blizzard has gotten greedy after WoW. Simple as that.
I can also already see them conveniently "adding up" all sales from Starcraft 2 campaigns and announce record sales for *Starcraft 2* - from all the kiddies buying the game 3 times. Kinda sad eh? But don't say you don't see it coming. If this works out they propably not gonna bother with tricks anymore for their next game and just charge 100$ right away. lol

Some companies make their products with a passion and reap the rewards. Blizzard has been such a company some long time ago. Other companies are more interested in "making money" and "making products" has sort of become a somewhat inconvenient necessity. That would be EA. And then there are companies who don't even bother with products anymore and rather try to make money directly. That would be the investment banks that are currently ruining our economy

Starcraft 2... now this is Blizzard moving closer to "EA" style companies. For a critical customer who actually cares from "whom" he buys, this move is extremely disappointing.
I certainly won't be supporting them with their greed. I won't be buying it at release and if... IF i buy it at all then that will be for 5 bucks in the bargain bin. I'm not in a hurry.

There's too many games to play anyways and several titles i am looking forward to... even, or especially from companies that i will gladly support by paying full price at release.
As far as Spore goes... i stayed far away from that after reading about the copy protection idiocy that EA tried to pull and seeing what their future plans are for the game i'm quite glad i stayed away, even if it was for a different reason lol.
