Why is a game about being a delivery boy so good? Is it the infrastructure building mechanic? Is it the batshit insane storyline? Is it the fact that every mountain is climbable? Is it the reserved use of combat and massive punishments for killing people?
Who knows, all I can say is I haven't had this much fun with a game in ages.
I looked at some let's plays and found it extremely boring. Looked just like a fancy walking simulator
It kinda is, but it's something that you need to play yourself to really get. The whole idea is that everything starts out super hard, but as you progress the game gets easier and you can use more structures and paths created by other people. You don't get the actual physical feeling of getting better just watching someone. You need to actually control the character and feel the progression from falling after stepping on a pebble to sprinting over a mountain with 200kg of medical supplies to save a dying mother.
