Illwinter (formerly Bogus) is the name of a small software company in Sweden composed of Johan Karlsson and Kristoffer Osterman. Illwinter's products include fantasy strategy games and an installer creation program for Linux. Illwinter's games are characterized by large amount of content, replayability, support for multiple platforms (Windows, Linux, Mac OS X and Solaris), good multiplayer support and simple – perhaps even outdated – visual and sound effects. The games are said to have a steep learning curve and a somewhat lacking user interface. Labor division within the tiny team is simple: Kristoffer Osterman creates the units, spells and descriptions while Johan Karlsson makes everything else work.
Both Johan Karlsson and Kristoffer Osterman have expressed their love for role-playing games, especially Ars Magica and roguelikes. Kristoffer Osterman teaches religion and social sciences as a primary occupation.
