Doubtlessly, StarCraft 2 is the longest-awaited computer game in history. Despite the 9 year-old age and its chipped resolution of 640x480 pixels, the game has been in the checklist of World Cyber Game for 7 continuous years, not to mention Starleague which was derived solely from the game's success.
An interesting study suggests that the Asian Financial Crisis in 1997 may account for the enormous popularity of the well-balanced game in Asia, especially Korea. I partly agree with this claim. I believe Blizzard's continuous support (the latest fifteenth patch was released in August 2007) and the game's well-balanced nature deserve such respect from gamers.
However, I think the game's successor is facing a situation never been discussed before. The original game (original here includes the StarCraft: BroodWar expansion) has become a legend that players are emotionally sticked with major units in the original game. “
Tempest didn’t feel right and that there was too much of an emotional connection with the original unit“, quoted from a developer of Starcraft 2, about the replacement of a new Protoss unit Tempest with the "original unit" Carrier. The key point here is that the Tempest makes no difference from the Carrier's idea of the real military unit, aircraft carrier. Even so, StarCraft players (like me) feel uncomfortable with the new name assigned to it, and emotionally want the original name back.
In fact, it is confirmed that the simplest attacking units of the three races in StarCraft 2 share similar appearances with those in the original game, they are Zealots (Protoss), Marines (Terran) and Zerglings (Zerg). The same situation is found in the highest tier units, Carriers from the Protoss, Battlecruisers from the Terran and Ultralisks from the Zerg.
To measure the successfulness of StarCraft 2 might be difficult, as the original game is general considered as perfect in game balance and so for playability. Personally, if Blizzard simply improves the resolution and the user interface of original StarCraft, the "new" product is definitely my cup of tea. Unfortunately, the real world is not that simple, overwhelming noise is expected for an imitative game like this.
Until now, I think Blizzard has found the best way to achieve this goal. While keeping many of the popular units in the game, it focuses on UI improvement and the storyboard. In order to comfort old-minded StarCraft players (like myself), Blizzard reassures gamers in unofficial channels that most (if not all) original StarCraft units will be editable in the map editor of StarCraft 2.
StarCraft 2 actually has just a none to little concerning the game play, provided that it will be released in 2008.
