Subject: [LINK] Ruby DSL for turn-based strategy game

"I continue to develop Dr Nic’s Civilizations game. This lead me to 
develop a DSL for the specification of game rules. You need to see this.

"Here’s an example definition of some terrain:

  class Desert < Terrain
    title           "Desert"
    letter          "d"
    graphic         "desert"
    movement_cost   1
    defense_bonus   10
    food            0
    shield          1
    trade           0
  end
  class Oasis < Desert
    title           "Oasis"
    special_code    1
    food            3
    shield          1
    trade           0
    graphic         "oasis"
  end

"An Oasis is a special version of the Desert terrain, so Ruby subclasses 
offer a compatible relationship."

I've written up why I used a Ruby DSL for this static configuration, and 
how it is implemented here:
