After reading your story, the only question I have is how much money can I give you for this game? Having a (12 year old) brother with a very similar cancer to yours last year, I still feel like I can only guess how hard it's been for you guys. You're truly role models for us all.
man the Crashlands spectrum is so broad. You could have a colloseum, fishing contests (if there is still fishing) defenses to your base etc at what point do you know when to pump the brakes and call a game done ?
