Just beat the game with Ending B, clocking in at 11 hours.
It's late here so I'm gonna save my full impressions for tomorrow, but I really was not impressed too much with the game. It had it's moments, but overall I would NOT put this above Homecoming. Even though Homecoming ripped off SH2's twist, and the otherworld amongst other things felt like the team was checking a list, I felt I would have rather had that than the trite that was in Downpour.
Downpour has the absolute WORST otherworld in the entire series, save for maybe Shattered Memories. Words cannot express just how fucking garbage each otherworld was. The story was not great, characters were dull. Tell me, just WHAT was the purpose of the mailman and DJ Ricks? Oh yeah, the mailman gave you a letter to let you know to get to a certain location, and Ricks also was there for the sole purpose of letting the player know he needed to get to a location. I would've rather have found notes on the goddamn floor guiding me to those locations. Useless.
Clearly I'm in the minority with this game, though.
