I don't know if's a good series, but that seems like a good deal.
Seems pretty fast BTW, didn't the last episode come out last month or so?
Yep, the last episode was released Sep 19th, so it went straight to 70% off after 14 days. Either it's a pricing mistake, or no one bought the later episodes at full price. After getting the first two chapters cheap in bundles, I held off buying the rest because I expected it to be discounted sooner or later, and perhaps others thought the same.
I only played a part of the first chapter so far, but I liked the story. It's a point&click paranormal thriller about a female FBI agent with precognitive abilities, and with unfinished personal business in her past. I liked the characters and the storytelling. Jane Jensen (of Gabriel Knight and Gray Matter fame) acted as "story consultant" - I'm usually careful with labels like these because sometimes they are just marketing stunts with no relevance for the game, but Jensen does indeed have close ties to the devs from other projects (and her daughter is doing the voice-overs for the main character).
Due to the low budget, the cinematic sequences are slide shows of painted pictures, or moving stills. Some players didn't like that, but I think it's a decent way to provide cinematic storytelling without an exorbitant budget. And a lower budget also means less influence from publishers, so there's a higher chance that the game will stay true to the creators' artistic vision.
