We've just added the trailer and gameplay overview for Mario & Luigi: Dream Team the upcoming Nintendo 3DS title due for launch this summer to our YouTube Channel. But I've also embedded it below for your convenience.
The gameplay of this title will shift between "reality" and Luigi's dream world and the setting for the game is a place called Pi'illo (a play on Pillow, because Luigi's asleep?) Island where our heroes have been invited for sightseeing (Mario, Luigi, Peach, Toadsworth and some Toads are all present).
