This is in my opinion the best game released on Wii to date all genres.
It is accessible enough for casual gamers (especially fans of New Super Mario Bros. Wii), but offers a depth of play and difficulty that can also meet the expectations of the most demanding players.
Having bought the first album there a few days, I find that the 2 games are quite similar in their gameplay but it is not annoying.
You can choose the style: either try to find all the hidden areas, all rooms ... or go directly to the end of the levels to face the boss. In any case, it seems almost impossible to explore everything the first pass, as the branches are numerous in each level.
The pace of Super Mario Galaxy II sometimes slows, when the game offers us to solve puzzles, but it is most often rampant, especially in levels whose configuration changes without warning. People often wonder how to achieve such platform or star apparently unattainable.
Some levels are very hard, but always comes back, especially because the playability is excellent. The game is never repetitive, because the difficulty is still gradual and new challenges are added to progressively.
The graphics for their part are beautiful, more beautiful I find that in the first episode.
The card system to navigate between levels reminiscent of the classic Mario and the New Super Mario series.
After 10 hours of play I think is very far from finishing the new Mario, but I can very highly recommend it for beginners and experts. Everyone will find his account.
Be careful though ... this game has a very big flaw: released just before summer, it may lock yourself at home and prevent you from enjoying the sunny days. In short, to buy emergency.
