Mario & Luigi: Dream Team Bros.
I am a huge fan of the Mario & Luigi series and this one does not disappoint. It has everything that I enjoyed in the previous titles with the addition of brand new mechanics. Love the inclusion of the dream world and how it subtlety pokes fun at the psychology of Luigi's subconscious. Super fun game. I can't put it down.
Just got to the part with Bowser. Now, things are bound to get really interesting.
