You should give Pikmin 3 a try! 1 and 2 were my favorite games as a child. It's sort of a strategy game and sort of an adventure game where you create an army of tiny creatures called Pikmin and battle large and colorful monsters to find treasure on a mysterious planet known as 'Earth'. (Of course, large is a relative concept, considering the character you play is the size of a quarter, and the treasures are things like bottle caps, children's toys, and costume jewelry.) The gameplay is fun, it has a wonderful sense of adventure, suspense and wonder, and the monster and world design really make the thing.
