A superior force fortified behind sandbags with mortar pits, dozens of men with things like Doomsday rocket launchers and sniper rifles begin shelling your home. You decided to manufacture excessive amounts of marble furniture and art. You have store houses overflowing with food. The word of the massive wealth of your village has traveled over the Rim and those who would have it for themselves have assembled to take it... You emerge, the beastmaster surrounded by a dozen different animals who do your bidding and take the fight to the enemy past your legendary impervious stationary defenses that are now useless in a desperate attempt to defend what is yours. You, your dogs, boars, boomalope and elephant go down in a hail of gunfire and grenades as the enemy shells come down on your medical ward housing bed ridden members of the colony who can't move out of bed due to multiple sicknesses and addictions. Everything you care about, everyone you care about, slowly blasted to pieces and trapped in rooms where fires rage at over a thousand degrees. The last thing you see are the barbarians beating and slashing apart the few animals who crossed the battlefield alive with uranium clubs and plasteel longswords... Just another day on the Rim.
You could have played a peaceful and relaxing city builder / colony sim but you decided to play Rimworld. Randy Random giveth, Randy Random taketh away... (You can customize the experience to be as peaceful as you want).
