I'd say sc. It doesnt matter if your acc gets hacked.

. Well if no acc hacks on d2, i'd pick d2
Hello ALL of Blizzard's games rock, but I like SC the best.
There was a topic about the exact same thing a while ago but I guess it got deleted.
I chose Starcraft! Because I do not own any other Blizzard games.
They are all pretty much the same to me.
Warcraft III is the best! better gameplay, more strategy, better editor with no limits and mod's work on battle.net, better battle.net(no winbots

) and better community.

actually there are winbots on wc3 ive seen them.
oh i dont like diablo online cause they are all hacked no one plays fair.
Starcraft Brood War!!! Always liked aliens and such things

well since this is a starcraft site...starcraft of course, i also like diablo 2 but oddly i haven't been playing it that much
SC BW...Nothing much more to say, except I also like World of Warcraft... Thats a good game! :-)
First Broodwar, then Diablo2, then Warcraft3. I omitted the older previous blizz games.
Diablo, Woot Woot. I been playing D2 for about 4 years now. And I still love playing the little bastard, But. I never have time to play that much cause of BW nowadays.
[center]StarCraft/Brood War. Although very buggy, and easily crash-able, a very great game. Plus, they actually put a huge storyling into it, and made some awesome single player campaigns![/center]
The way I rate them:
Starcraft Broodwar - first
Warcraft the Frozen Thrown - second
Diablo II Lord of Destruction - third
So I vote Starcraft.
But what sense is there in voting "All"? The quastion was which is the best one, there can be only one which is the best, those games are not 100% identicle after all...
