When you start a new game of Dwarf Fortress, a world is generated. Not just a map, but a world, with its own legends, characters, factions and historical wars. It’s one of my favourite openings to any game and gets me far more hyped than any fancy cinematic intro.
Wouldn’t it be great if Crusader Kings II [official site] could do something similar, rather than sticking to actual historical beginnings? Thanks to a modder who goes by the name Yemmlie, it can. The CK2 Generator can create alternate histories, simulating the appearance and development of cultures, religions, languages, characters and all the rest. It defaults to the vanilla map but if you want a random world to play on as well, that’s supported.
