Alright so I finally have been p[laying enough of this game over the last 3 weeks to make an opinion on it.
The campaign is anything but the epic, amazing, "holy shit holy shit" deal that Blizzard was try to push. I played through it on Hard and it took me about 10 hours with he only mission I failed once being the very last one. Too easy, too short, and some arcs shouldn't have been there at all. The worst was the colonist arc, not only did it not have ANY relevance to the story and was just plain obvious filler, but the missions were also extremely boring and routine. Tosh's missions were also just plain filler, but at least some of them were pretty interesting to play through.The ending was such crap it wasn't even funny either.
Furthermore we got 4 cinematics, 3 of which we had already seen (Finlay's release, Zeratul vs Kerrigan, and Sarah being abducted) and none of them even came close to the ones that were in WC3, like the end of the Orc and Human campaigns. Everything else was some crappy in-game engine bullshit that Blizzard tried to pull off.
Multiplayer wise it's the exact same as it was in beta. Bnet2 is still a horribly shitty service due to all its missing features and restrictions on custom maps. The multiplay itself is good but it's not anywhere near SC1's, because while I wasn't all that great, it doesn't take a pro to realize that SC2 is half the game game SC1 is. The worst is that when a tactic that takes genuine skill and that annihilates me starts to emerge, Blizzard patches it out.
In the end this game is not even CLOSE to being worth $60. I would have had a hard time justifying the buy even if it was $50. With it's crappy and lackluster singleplayer, dumbed down multiplayer, and the horrible, borrible, Battle.net 2.0 SC2 is one of the biggest disappointments I have bought. It definitely trumps SPORE in "letdown" factor.
