Question: Afrikan tähti and Twilight Imperium are what types of games?
Context: Inkan aarre (Finnish for "The treasure of the Inca") is a 2005 Finnish board game, designed by Kari Mannerla as a direct sequel to his 1951 board game "Afrikan tähti". Twilight Imperium: The Role-Playing Game is a role-playing game published by Fantasy Flight Games in 1999. In ancient Roman religion and law, the auspicia maxima (also "maxima auspicia") were the "greatest auspices," conferred on senior magistrates who held "imperium": ""auspicium" and "imperium" were the twin pillars of the magistrate's power" "(potestas").  Only magistrates who had "auspicia maxima" were entitled to begin a war and, if victorious, to celebrate a triumph.  The "auspicia maxima" were reserved primarily for consuls and censors, but these were two different types of auspices.  Consuls and censors were not colleagues, and the censors lacked military auspices "(auspicia militiae)".  Praetors, however, held a form of "auspicia maxima" and could also lead an army, though their "imperium" was lesser than that of the consuls. Twilight Imperium is a strategy board game produced by Fantasy Flight Games.  It was designed by Christian T. Petersen and was first released in 1998.  The game is in its third edition (2005), which has large changes over previous editions.  This edition also has two expansions – "Shattered Empire" released in 2006, and "Shards of the Throne" released in 2011.  It is known for the length of its gameplay (typically greater than 6 hours), and its in-depth strategy (including military, political, technological and trade). Mag Blast is a spaceship-themed strategy card game, produced by gaming company Fantasy Flight Games.  The first edition was set in the universe of "Twilight Imperium", a board game made by the same company.  The game is playable for 2-8 players, and is described as "a game of screaming space battles" Shards of the Throne is the second expansion to the board game Twilight Imperium, both of which were designed and published by gaming company Fantasy Flight Games.  It was released in May 2011. Kari Mannerla (January 9, 1930, Helsinki, Finland – July 12, 2006, Helsinki, Finland) was a Finnish board and card game designer and advertising agency executive.  The most famous game designed by Mannerla is the board game "Afrikan tähti" ("The Star of Africa"), the idea of which he began to develop in 1949.  The game was published two years later.  Mannerla made up the name of the game when reading an article about the biggest diamond in the world, the Star of Africa, discovered in South Africa. Afrikan tähti (] ; Finnish: Star of Africa), known in Swedish as Den försvunna diamanten (The Missing Diamond) or Afrikas stjärna meaning ""the star of Africa"", is a Finnish board game designed by Kari Mannerla originally in 1951.  It has been one of the most popular board games in Scandinavia for decades. Shattered Empire is the first expansion to the board game "Twilight Imperium", both of which were designed and published by gaming company Fantasy Flight Games.  It was released in December 2006. Imperium is a Latin word which, in a broad sense, translates roughly as 'power to command'.  In ancient Rome, different kinds of power or authority were distinguished by different terms.  "Imperium" referred to the ability of an individual to command the military.  It is not to be confused with "auctoritas" or "potestas", different and generally inferior types of power in the Roman Republic and Empire.  Primarily used to refer to the power that is wielded, in greater or lesser degree, by an individual to whom it is delegated, the term could also be used with a geographical connotation, designating the territorial limits of that "imperium".  Individuals given such power were referred to as curule magistrates or promagistrates.  These included the curule aedile, the praetor, the consul, the magister equitum, and the dictator.
