I hate my dwarves in dwarf fortress.
By now I lost at least 15 dwarves because they tried to fight a fish when they can't swim.(And then at least 20 got injured or killed trying to retrive the corpses, or items on the corpses)
And 5 or 6 because they walled themselves in.
And about 10 got minor injuries after falling down a hole they were digging themselves.
It's a little ok though, more new dwarves arrive then old dwarves die.
Also, they are now using a capitalist system, there are 50 coins for 120 dwarves.
