When it comes to remaking or porting games, they can be outstanding like Metal Gear Solid: Snake Eater 3D, they can be OK like Street Fighter 2 Collection or they can be really craptastic like Sonic the Hedgehog Genesis for the GBA. Kirby: Nightmare in Dreamland is an outstanding remake of Kirby's Adventure.
There are new features in this game, which include: multi-player, new mini-games, new game mechanics, the addition of Meta Knightmare and new enemies in replacement for the older ones. There are a lot of things I love about this game which include the updated graphics and gameplay, that Nintendo managed to update the music and make it sound better (Unlike Sega who ruined Sonic 1's music in their remake of Sonic 1), the new mini-game modes and much more!! Kirby: Nightmare in Dreamland is an awesome remake of Kirby's Adventure, which isn't surprising since Nintendo are geniuses when it comes to remaking games. If you do not believe me, go and play this game or any other remade games by Nintendo like Super Mario 64 DS, the Super Mario Advance series or even The Legend of Zelda: Ocarina of Time 3D! But I digress...
I highly recommend Kirby: Nightmare in Dreamland for anyone looking for a great multi-player title or anyone who loved Kirby's Adventure.
