Why we think so

These three form an achievable progression for a new player—join a faction to get diplomatic/military support (Friend in Need), deepen your game knowledge by fully researching a doctrine tree (Master of War), and unlock mid-game construction strength with Construction V (We'll build it in a day) so you can capitalize on doctrine and faction advantages.
