[1] Formerly just "SystemSoft", they have a long series of mainly military strategic simulation games (generally hex-based) popular in the Japan market.

Notable among these are the many Daisenryaku and Master of Monsters series games that have been ported to multiple platforms from PCs to consoles.

Only a handful of the dozens of games in their portfolio have ever been translated to make it to English-speaking markets, including two Master of Monsters games for the Sega Genesis and Sony PlayStation ("Disciples of Gaia"), and some of the Daisenryaku games (Iron Storm, Daisenryaku VII, Daisenryaku VII Exceed).

SystemSoft has produced many wargames that are from the perspective of the Japanese Military, circa World War II.

Similarly, if less controversial, is the guaranteed inclusion of the Japanese Self Defense Forces in modern wargames like the Daisenryaku series.
