Warioware: Touched is one of the best "pick up and play" game compilations I've seen for the Nintendo DS. The title consists of roughly 180 minigames, sorted by theme. After about two hours of unlocking the stages, "Touched" basically turns into the perfect time-waster, good for players who want to spend hours improving their high scores, or just want to kill 15 minutes at a time.
Touch screen controls are very responsive, and all of the minigames utilize touch controls or the DS's built-in microphone exclusively. Sound and graphics, while nothing too fancy, do the game justice, and the art direction is quirky enough to really distinguish the game from similar titles.
Warioware: Touched is definitely a must own for any DS owner. It's unique feel elevates it's rapid-fire, addictive gameplay to make the package as a whole something that can't be missed.
