All these games are great, with really good story and extremely fun, but Nintendo could have done so much better, for example, Super Mario 64 could have been widescreen and 60 fps, and Super Mario Sunshine could have been 60 fps too.
The game is a little bit overpriced too, I know that these are 3 incredible games, but paying 60€ for these games is ridiculous.
The soundtracks feature in Super Mario 3D All-Stars is cool, but I can't barely see any usage for that.
Controls were really good in my opinion, the only downside of them is using the touch for Super Mario Galaxy in portable mode, I found it very unconfortable and overall not a great experience, I recommend playing Galaxy on the TV.
