SimonG: Apart from Warcraft 1, Diablo, Starcraft (I consider the three totally unique races innovative) and the Three Vikings ...
hedwards: Warcraft 1 wasn't really that innovative IIRC.Looking at the Wikipedia it looks even less innovative than I would have though. Diablo seems similarly poxed. It does get credit for creating the point and click ARPG genre, but honestly, it's not really fair to call that innovation as the genre properly goes back to Rogue and throwing an interface around it with a mouse was going to happen eventually. It's not really something that's terribly innovative.
Star Craft, you have a point there, whether they should be credited for doing the work to make it actually work or coming up with the idea, it was innovative for the time and the game seems to hold up pretty well.
I'm not so sure about the Lost Vikings, I'm not sure what they really innovated there, Gobliiins had already been released and did the 3 character, unique ability, problem solving thing as well.
I stand corrected on the Lost Vikings, I thought they were the first on that concept. But I still think that Diablo was pretty damn innovative. There is a reason that many games of the late 90s were called "Diablo clones".
And I also thought that Warcraft was older, I knew it was older than C&C. Still, especially with the Warcraft and Starcraft series Blizzard has made a very strong mark on the RTS genre.
You could always e.g say that Wolfenstein predated Splinter Cell, as many core elements are seen in both, yet I still wouldn't call Splinter Cell a polished version of Wolfenstein.
And, in general Blizzard was on the forefront of multiplayer for "casual gamers". Diablo and Starcraft were among the first truly massivley multiplayer games.
In recent year (well, since WoW) nothing really breathtaking was done by them, but that shouldn't throw a negative light on their earlier accomplishments.
And they made the first game were I could shoot orcs with a shotgun!
