Not surprising, but generally good news indeed. It's so far away though... Hope it combines the tone of 999 with the mechanical improvements of VLR!

How good is the story for this game?

It's enjoyable novel schlock: don't expect Tolstoy, and it gets a tad muddled when you think about it too much, but overall it's a fun series of games. Just be warned that the two games are different in tone: the first is closer to a survival-horror novel, while the second is closer to a murder mystery. Either way, you should play them both, preferably in order.
