Gothic is rated 18+, but that's nothing to do with the content in the game. It's because of the endless torrent of red-faced swearing it inspired from me when playing it. In fairness, Gothic enjoys swearing at me too. Almost as much as it enjoys killing me, confusing me, withholding crucial information from me, and wasting my time. Stick with it and you'll find an incredibly rewarding remake of a true original. But dear God, who wanted a game that was like Kingdom Come Deliverance except less user-friendly?
Unlike Kingdom Come, we're very much in fantasy land here. The King is at war with an army of orcs, and he's got all the prisoners in some grim mining colony endlessly collecting ore to make weapons. But, a magical explosion suddenly leaves all those prisoners trapped beneath a one-way magic dome. An uneasy truce is forged between the King's forces and three rival camps all living under this literal thunderdome.
