A game with a fantastic concept that was very poorly executed, full of bugs and extremely difficult.
The game remains largely unpatched since release for most of the inherent problems.
This is a family dynasty simulator in which you economically grow your family via businesses and diplomatic relations within your townships. You can take office in local parliament, ultimately running the town (this is extremely, extremely difficult to even get close to this). You run business' of various trades, IE a Pub or a Blacksmith, you find a woman to marry, and have children with her, growing your clan and ability to pick up new business through your children (once they are controllable and at apprentice age).
The Guild II has a relatively steep learning curve, and really is a good example of a difficult rts/rpg from early 00's.
The Guild II has a nice consistent fantasy middle age art style and it would be nice to see the game remade in the modern day in working order for its conceptual ideas and simply the fact that nothing really like it has come out since.
