Some sequels radically reinvent what has come before; others simply buff up a formula that already soars. To suggest that Starcraft II: Wings of Liberty does only the latter and not the former would be to sell short the fresh ideas and exciting gameplay that makes this superb real-time strategy sequel so enjoyable. This package delivers more than simple fun--it serves up incredible amounts of variety, from the cinematic and multifaceted campaign to the competitive and tightly balanced multiplayer. You might scoff at the fact that the game only includes a single campaign and, perhaps, at the high price point (the game retails at $59.99; $10 higher than the average PC game). But these are nitpicks, forgivable quibbles in a high-quality game that provides plenty of bang for the buck. Starcraft II is the natural next step for the series: it both embraces and updates the core components that made the first game a huge hit while layering on important features that give the game endless replay value, both online and off. This is one of the finest real-time strategy games in years, and whether you're new to the genre or have been studying Protoss build orders for the past decade, there's something here to delight you.
