So...  What do you get when you combine classic Mario gameplay and new polished modern graphics?  This game.  This game combines everything you know about 2D Mario and improves on it, just like it did 2 decades ago.  This is a great game overall, and the next few paragraphs will tell you the reasons why.

It's easy for anyone to play.  Mario games have slowly done this more and more over the years, but a newcomer to Super Mario can play this game, probably finish it, and beat Bowser eventually.  As with the more experienced Super Mario players, they can find all the secrets that this game hides and beat the entire game.  And if anyone has any trouble getting through a level, and they lose 5 times in a row on the same level, a Super Block appears.  Hit it, and a computer Luigi will play through the level for you.  You can even hit the block, have the computer player play through some of the level, and then start playing again.  Very nice feature.

What I think is the best reason to buy New Super Mario Bros. Wii is that there is now a variety of suits.  The new power-ups include the Mini Mushroom (from DS), Propeller Mushroom, Penguin Suit, Ice Flower, etc. while introducing classic Mario power-ups like the Super Mushroom, Invincibilty Star, Fire Flower, etc.  What's really interesting about this is that sometimes you need certain power-ups that aren't in the level you're playing to find the secret in the level.  Say you need a Propeller Mushroom to get up into a pipe.  But there aren't any Propeller Mushrooms in the level.  Well you need have one in storage (yes, they have item storage in this game) or finish the previous level you played as the power-up you want.  This really got me into the game.  For me, this is the main reason I would buy this game.

The only downside to this game is that once you beat the game, defeat Bowser, and find most of the secrets, it just feels plain boring.  Yeah, the lasting appeal in this game is not good.  Don't get me wrong, I love this game, but no game is perfect.  Although, lasting appeal is one of the most important ingredients in a good game, and this game just doesn't have it.  I feel that you shouldn't rush through this game, and enjoy this game while you have it.  But this game is the first Super Mario game to feature 4-player gameplay, so you can play alone, with 2 players, 3 players, or 4 players.  That improves the lasting appeal slightly.  Believe me, multiplayer is fun in this game.

If you're on the fence about buying this game, you should get it if you want a great game that brings you back to the 8 and 16-bit video game era.  If I had to describe why to buy this game in one sentence, I would say that "Classic Mario is back... completely!".  I feel that the only thing wrong with classic 2D Mario is that it didn't have lasting appeal once you beat the game.  I feel that they could've gotten rid of that part, and that part only.  This game would've scored even higher that an 8.5/10, but it's just because of the lasting appeal.  Just because it doesn't have lasting appeal when you beat the game doesn't mean this isn't a must-buy.  Because it is.  I was impressed, and so are a ton of other people, so my opinion is this game is a great game, so if you're on the fence for getting this game, you should get New Super Mario Bros.
