Oh, I highly recommend them! Most people (including me!) consider Explorers of Sky to be the best game, since it has a wonderful story, good post-game and a great choice of starters to choose from. :) Otherwise, between the two 3DS games, Pokémon Super Mystery Dungeon is the better choice, since it has been improved in many ways. It can even be quite difficult sometimes for people who enjoy a challenge!
By the way, it's been really nice seeing you as an active presence in Trivia! Keep it up! :)
