I guess, there are SO MANY MORE MISSIONS in a single episode of Starcraft 2 than the entirety of either SC or Brood War. Thats not to say the story is any better, I think its worse - more dragged out and pointless, the worlds been WoW-ified and is less grounded and realistic and more LE EPIC. Still, great games, all of them :D
Citing Blizzard in this case might not be the best example!! somewhat dominant in the MMO market :p In relation to StarCraft though I still dislike Blizzard for opting to turn 1 game into 3 games, drip feeding the content so they could charge gamers much more for this one game than they had for buying the first. If they could do all 3 sides in the first game, no reason other than greed to split it into 3 games for the sequel.
Is it safe to buy from them? Im sort of afraid.
I still play Warcraft 3 TFT :)
No you cannot. This is Blizzard game :) Personally I feel Steam is too big a monopoly & we need competition.
