>>1366937>After having played the first game almost non-stop for the past couple of days, I've gotten what I imagine is every ending.There's A, B, C, and D, and an ending with each heroine, each of which has an optional bad extension.>Does the second game help explain what happened in the first one?
BS2 follows ending D of BS1. Eventually you should be able to figure out what happened, but it takes some digging. BS2 is far more obscure about its story and mechanics than 1 was.>How many playthroughs should I expect if I want to see everything?
Without spoilers? A lot. There are 7 endings with 4 being easy to get and the other 3 taking some effort. If you load a save just before the ending you could potentially see all 7 endings in one playthrough. Fortunately the fairy tale books are not required for any endings in 2.>Is there a happy ending this time?
Surprisingly there is, though it isn't clear whether Grimm is still trapped in the time loop.
