An adventure game classic.
The Blackwell Legacy is an emotionally charged point‑and‑click paranormal noir, where the cigarette smoke is replaced by ghost‑light and the case file is made of unsolved murders and all the things we never get to say. The storyline is anchored by Rosa’s isolation and Joey’s sardonic presence, two characters bound together by a supernatural inheritance neither fully understands. From start to epilogueous lingering what drives it isn’t the mechanics but the mood. A haunted New York, a reluctant medium, and a partnership forged in grief, impositions of will, and perceptual responsibilities. “There are known knowns, things we know that we know; and there are known unknowns, things that we know we don't know. But there are also unknown unknowns, things we do not know we don't know.” ― Donald Rumsfeld, Known and Unknown I have to do another run through for the rest of my trophies, but honestly, I am looking forward to it.
The gameplay is fine I guess, but the game lacks sign posts, and it also lacks a way to turn the absolutely asinine music off. The mixing is so bad, that sometimes the dialogue is just drowned out by music, or you have to turn the volume down to avoid the music that's mixed SUPER LOUD, but the voices are mixed super quiet in comparison.
It's a couple hours of gameplay for $5, maybe stick to getting it on sale.
I've always loved point & click adventures, and this one is pretty great... VERY short... about 2 hours of gameplay in total. The story is good and intriguing; the writing could be a bit stronger. There are points where a conversation seems to flip very quickly or be over very abruptly... like trying to convince someone they go from "Absolutely not!" to "Okay Sure!" after just one sentence... people just change their minds at the drop of a hat... even in the ending... which could have benefitted from more verbal sparing rather than "You said no... so I'll do this one simple action and now you've completely changed your mind" it made the ending feel somewhat cheap... but don't get me wrong, the premise is good and overall its a good game... some of the voice acting is a bit ropey... one character you can hear rusting in the mic when it was recorded... The biggest problem I had though... was the music... The actual music itself wasn't bad... but it was VERY loud in some placed and drowned out the dialogue... and there is no way to turn it off, or even turn it down for that matter. I hope this issue is fixed in the later games.
