The Legend of Zelda: Phantom Hourglass review at IGN.

"Over the years the Zelda franchise has evolved quite differently depending on if you're looking at the console side of things, or just the portable world. While the "main" series - if you can call it that - has progressed from classic 2D top-down to 3D, continuing to deliver the same enchanting, epic feeling from iteration to iteration, Link's portable ventures have been a bit skewed. It began humbly with Game & Watch, moved then to Link's Awakening - a pure pocket Zelda - only to morph into the Capcom-created Oracle of Ages/Seasons world, evolving yet again into the Four Swords-like design of Minish Cap on GBA, and finally residing here on DS with The Legend of Zelda: Phantom Hourglass as a fully touch-based, 3D Zelda set in the world of Wind Waker. Is it the Zelda many of us expected? No. But the legend still lives on."
