As part of the oh-so-slow mission to pull Mrs Grim... deeper into video games, I suggested we do a playthrough of FireWatch (where I "drive" and she watches). We finished it last night, Mrs Grim... went to bed, and I turned on the audio commentary special feature and completed it all over again.
What an utter delight this little game is. It's beautiful, it's tense, it's lonely, it's wonderfully voice-acted (as it would have to be, considering the only real interactions you have are on a radio). Depending on your choices, the start of the game ranges from "sad" to "heart-breaking".
I would certainly put it in the "interactive story" category, but it's way more "game" than something like Everybody's Gone to the Rapture. The story itself is also wonderful (apart from one bit which I'll go into in the next post as a spoiler).
It's also the first game I've ever 100%ed. Check me out.
But yeah, FireWatch is cheap and short* and wonderful, and I can't recommend it enough.
* This is a good thing in the book of Grim.... It lasted about five hours (plus four more to do it a second time. The audio commentary was really interesting, too!).
