Human: Fall Flat seems like the kind of game that was conceived at a party where someone asked “what would it be like to control a character who's already drunk?” Unfortunately, the game falls a wee bit short in terms of depth and gameplay. While it does have bits of drunken fun and charm, it would be better used as a mini-game in a larger game, similar to playing the Doom mini-game in Wolfenstein. There's some fun and experimentation to be had in Human: Fall Flat, but be prepared for the hangover that follows.
Crossout reminds me of the first vehicle I owned, which was a 1970s Volkswagon Beetle hand-me-down. It didn't look like much at first and it definitely had its share of problems, but I had a lot fun driving it. Soon I discovered that the more time I dedicated to fixing and upgrading it, no matter how monotonous, the more fun it became. Some problems were never fixed, but eventually I was proud enough to take my custom car out in public and show it off.
