Yes, the game is extremely unbalanced. See this topic to see the other side of the spectrum: https://community.7daystodie.com/topic/36511-how-can-the-game-still-be-this-unbalanced-its-been-10-years/
Game can either become way too easy or way too difficult depending how you play, no matter the difficulty setting you set the game to. Unfortunately, the devs expect everyone to play a certain way and if you don't, you end up with one of those results. So you're either on a straight and narrow path or your enjoyment of the game gets ruined with unbalance. Who would have thought that an open world sandbox game had to be played a specific way?
But hey, what do I know... I'm just a kickstarter for this game. I'm sure the "experts" will chew me out and defend the game for this post.
