Block wargames are not restricted to any one publisher but Columbia Games are the one who produces a vast and varied range of only Block boardgames. We find that they are a simple and effective method of generating a level of fog-of-war not present in many other boardgames and this in turn leads to a game that is both enjoyable and tense (and more enjoyable for that). You could easily delete 'tense' and insert the word 'stressful'.
Block games within the Isle of Man's wargaming community do tend to create a certain love it or hate it polarised viewpoint however those who love them rarely find satisfaction with other boardgames nowadays (though perhaps surprisingly tabletop figure gaming is still popular across the board so to speak).
So what are your thoughts? Have you ever played and found them wanting? Do you too enjoy them? What about other manufacturer's Block wargames?
If the current speed of publication by Columbia Games is anything to go by they most certainly are popular....
