Illwinter Game Design (formerly Bogus) is the name of a small software company in Sweden composed of Johan Karlsson and Kristoffer Osterman. Registered officially as a company in Sweden since September 27, 2001, Illwinter's products include three fantasy strategy games and an installer creation program for Linux. Illwinter's games are characterized by large amount of content, replaybility, support for multiple platforms (Linux, Mac OS X, Solaris and Windows included), good multiplay support and simple, perhaps even outdated, visual and sound effects.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.
Based in Malmö, Sweden.
