Fun game the whole series is probably the best series on the GBA.
Graphics: Above average i like em 8.5/10
Music: The music is pretty good not the best though 8/10
Fighting: MMBN uses chips to fight ( computer chips not food chips ) it's interesting and you have to work to get the chips or you can buy them in shops for the mmbn currency Zennys. The fighting on the game itself is fun and interesting making you think of strategys. 9/10
Bosses: Alot of bosses when you first do this you have a high chance of death but later you do better and can defeat them easier. 8.5/10
Multi-player: Multi player is when another person has MMBN and a gb link cable. You can do practice where you fight and don't lose a chip. Or real where you fight and winner gets a random chip depending on how he/she did.
Storyline: Great storyline will have twist and turns till the end and even after the end! 9/10
Overall: The game doesn't have as much as the later games but it is enjoyable and i HIGHLY Suggest this game to anyone! 8.5/10!!
