Okay, so Firewatch is not a short game. It's not a very interactive game, either. Quite a linear adventure with the illusion of choice, more so than the Mass Effect series. And that's saying something. Can't say that I hate the experience either, considering its story-centric design. I don't mind such games every now and then, but nowadays, I do prefer to stick to movies or just anime when it comes to good stories. Games can be quite tiresome when I have to do all the work to get through the story. And we can forget about books and visual novels either, considering my short attention span. I put the Umineko no Naku Koro ni Chiru VN on hold shortly after I began reading it. I digress...
Anyway, I also got this game called "Downfall" that's supposed to let you mold the main character in a number of ways, depending on your choices. I like that kind of game, but all too often, it's just false advertising (like Firewatch).
