EU4 Chess

As the name suggests, EU4 Chess combines the classic game of chess with your normal game of Europa Universalis IV. This mod allows players to engage in actual chess matches, either against another player or the AI, enhanced by a unique chess engine developed specifically for the mod using purely in-game modding resources. This idea was created and directed by the mastermind Sol_InvictusXLII, who has initiated and brought this concept to life.

Post Finem Shattered Pages

Shattered Pages is an alt-alt-history submod for the highly acclaimed alt-history mod Post Finem. Its main goal is to present and bring to life unhistorical scenarios that are perhaps (definitely) too out of the ordinary for the main mod, while providing a rich and full experience. It leans on myths, legends, and tall tales for its inspiration and seeks to shape them into plausible, though not necessarily likely, stories. It dares itself to explore the unorthodox and perhaps even dabble in the supernatural.
