Review: parfait, un vrai plaisir pour mon fils de construire ses lego et par la suite utiliser ces pieces pour les constructions de son imagination.
Review: Siempre he confiado en los juguetes de la marca Lego y no me han defraudado nunca. Y éste no iba a ser menos. Juego-puzzle de más de 300 piezas para montar, adecuado para niños mayores de 7 años (y algún menor avispado), con instrucciones perfectas de montaje, con figuras como un perro, un árbol animado, personajes y elementos móviles como la tumba, la estatura,... Descargada la app de realidad virtual, Lego Hidden Side (yo tengo iOS y sin problemas), siempre que tengas un móvil compatible con AR (realidad aumentada) podrás interactuar con el juego y el pequeñ@ se lo pasa genial. Está muy bien conseguida. En definitiva, seguiré confiando en Lego para éste tipo de juguetes que no tienen competencia. Aproveché un precio con descuento. Muy satisfecho con la compra para un regalo de un familiar.

Für Lego ist man ja nie zu alt, und daher packe ich auch heute noch gerne mal das Lego aus und fange an zu bauen. In meiner Kindheit waren die Themenwelten Castle, Piraten und City das Maß aller Dinge, zumindest für mich. Leider sind diese Sets nicht mehr wirklich verfügbar. City ist natürlich nach wie vor sehr umfangreich und sehr interessant, allerdings fehlte mir bei den aktuellen Themenwelten das gewisse Etwas. Bis jetzt, denn nun habe ich die Hidden Side Sets entdeckt. Wobei ich direkt sagen muss das ich die App-Spielerei gar nicht erst benutze. Mir geht es um das gruselige Thema, dieses gefällt mir wirklich sehr gut und ich finde die Sets wirklich gut umgesetzt. Dieses Set hier ist zwar eines der kleinsten, dafür aber mit das schönste, es beinhaltet ca. 335 Teile und insgesamt 4 Mini-Figuren (wenn man Spencer den Geisterhund mitzählt sind es sogar 5). Aufgebaut habe ich es in ca. einer dreiviertel Stunde. Etwas unglücklich finde ich nur das in jeden Set mindestens eine der Figuren des Jack Davids und/oder seiner Freundin Parker enthalten ist. Kauft man sich nun mehrere Sets, was ich getan habe und was wohl auch viele andere machen werden, dann hat man hinterher gleich mehrere dieser Figuren daheim. Aber okay, vielleicht besser so, als andersrum. Das Aufbauen ist halt typisch Lego, es macht einfach Spass und ich bin immer wieder erstaunt was man mit Lego alles anstellen kann. Die Details und alles, einfach klasse. Auch zu diesem Set gehören ein paar Aufkleber, diese sind aber nummeriert und einfach aufgeklebt. Nach den ganzen altbekannten Themen- und Lizenz-Sets ist Hidden Side für mich eine großartige neue Legothemenwelt von der ich hoffe das es davon noch viele weitere, und größere, Sets geben wird.
