Gameplay is the crucial component of any good game, right? Well,
Rayman 2 has gameplay down pat. Of course, you are Rayman, unwitting hero who is once again called upon to rescue his friends. Robo-Pirates have kidnapped all of the Teensies and it is up to Rayman to travel across the land, freeing each of his friends from captivity and collecting helpful lums (powerups) along the way. Of course, he'll encounter all sorts of memorable characters along the, my favorite being Murfy - but mainly because he whispers like a friend of mine did with tonsillitis. It's cute. Coincidentally, Murfy becomes your advisor, and you can call upon him at various times during the game for assistance. In addition to the standard Rayman-esque platform fare, there are levels where you'll call upon Rayman's your more interesting skills such as navigating a swamp at high speeds while being dragged by a friendly (but careless) sea creature. Good stuff. The requisite puzzles are there and they are appropriately challenging, and the game has scads of areas, providing plenty of gameplay. This port from PC is a top notch job by Ubisoft.
Also, be aware that there are special features found only in the Sega Dreamcast version. There are multi-player mini games which can be unlocked by completing certain areas, so be on the lookout for those.
