You can play this successfully for 40 hours, and then if the game decides that you're going to lose, you'll lose everything. In the late game, you're just a couple bad rolls from losing everything you've accumulated. No strategy can compensate for missing 10 attacks in a row. And there's a non-zero chance you will. Any positive review you've seen of this game is from someone who just avoided the pitfalls of rolling poorly in a late game mission. If you spend money on this game, good luck. I hope you get lucky and avoid having 40 hours of gameplay wiped out by poor dice rolls.
