Controlling Ecco in this game is a snap. Holding down A will show you a map of your location, which will come in handy a lot. There are also plenty of Glyphs scattered about, and they either help you out, give you bum advice, or block your way. Another neat thing is the use of dia- er, monologue. But the heavy use of undersea jargon makes it forgivable.
Graphics are very colorful and vibrant.
Ecco looks almost photo- realistic, and other sea creatures appear like they've just jumped out of an issue of National Geographic. The Vortex aliens look very H.R. Geiger-esque. The levels look great too. But it didn't annoy me much. Overall, some will be put off by this game's repetitevness, but for the rest of us, Ecco the Dolphin will give you lots of old-school fun.
