This was just a great fun little game to play. The art style and music is top notch. The only reason I didn't score this games higher was the total length and difficulty. This game will only take you about 5-6hrs. to beat and the level difficulty is so easy a 5 year old can play (they did that on purpose so they can). This is a great start to Mario in HD hopefully some tougher games come in the future.
The homage to old school Mario at the end was awesome.
If you're one of those gamers who are anti-Nintendo and stuff, don't play this game and don't complain about it. If you're a loyal Nintendo and Mario fan like I am, you definitely need to get this. Unlike New Super Mario Bros. Wii, this is not a clone of the handheld entry, it's so fresh with its HD graphics and new courses and worlds. I don't care about HD, it's not a necessity for me, but the HD does make the game pop. I suggest getting a 1080p tv for the game, even if you're not an HD fan either, it just makes things clearer and easier to read. Of course you can always just use the gamepad screen since it has everything that's on the TV screen for some reason. All in all, it's a solid platformer with all the famous Mario elements plus many fresh new ideas that keep it going, I highly recommend it.
