Res Publica is a freeware political simulation game developed by Heiko Dittrich and released in the 1990s. The game, in German, allows players to manage a republic, making decisions on policy, economy, and governance. Players must navigate elections, handle public opinion, and deal with political opponents. With a minimalist interface, Res Publica offers an engaging challenge for those interested in strategy and political simulation, all while reflecting the complexities of running a government.
