"Zero Escape (ZE) is easily one of the best games I've played since, well, its prequel 999.
Strictly speaking, you don't have to play through 999 (that's 9 Hours, 9 Persons, 9 Doors) on the DS to enjoy Zero Escape: Virtue's Last Reward (ZE), but you absolutely should for two reasons. First, like any pair of games, books or movies, experiencing the originals and then the sequels makes both experiences more complete and rewarding. Second, 999 is a stunning achievement and my favorite handheld game (surpassing Hotel Dusk)."
