I find it strange that some people seem to be coming to the conclusion that games don't have to be "Fun", as if it's some sort of new revelation. Games have never HAD to be fun, they've had to be compelling and rewarding in some way. The by-product of that is fun, more often than not, but the real goal is surely satisfaction from the experience, which can be reached in different ways and take various forms. In the same way, some people will derive fun from activities that others do not. Perhaps we should simply be asking, what about this experience makes it compelling to play, that lets us get something out of it as a player? This War of Mine is not "fun" per-say in the traditional sense, it is however compelling and rewarding. I'd certainly encourage people to use the term "fun" less when describing a game if they can't back up why exactly they experienced that feeling, but that also applies to every other feeling they experienced in the game. If you can't tell people why you felt that way, you're not much use as a critic.
