New super mario bros is a great game, and it's a great improvement to the past series!
Gameplay 8.5/10 - The gameplay is overall pretty good. After you beat the game, theres really nothing much to do, except mini games, and you can replay the levels. The game is easy though, don't expect this to be a challenging game. It is easy, but some of the levels can get hard, esspessially the last level. Some of the levels are fun, although some of them may seem to short. Overall the gameplay is good enough.
Sound 9.0/10 - The sound is pretty good, some of the songs may be a little boring, but on some levels like the first one. It gives you a nice little remix of the new super mario bros theme. Overall it's pretty good.
Graphics 9.2/10 - The graphics were awesome. I love the 3d effects, and some of them are great. Although mario does look a little blurry, it's pretty good.
Overall 8.5/10 - This game is fun, and it's definitely worth playing. But when you beat it, there really isn't much to do. So you may get bored of it after you complete it.
