Several of you have asked what 'Warhammer' is. How long have you got?
Here is the shortest version: Past generations played with tin soldiers, re-enacting historic battles, or creating their own. 'Warhammer' is a kind of modern day version. It is based on a fantasy world that is populated by different races (there is a 'Lord of the Rings' version). Players have 'armies' of figures and play against eachother, using quite complicated sets of rules and scenarios. This is not for the faint-hearted. It takes strategic planning, maths, high level reading skills, artistic ability, etc. Most of the boys (11-18) who come to the club are highly intelligent, but not very good at communicating. Through the game they blossom and all awkwardness is forgotten. They learn/practice new skills, or improve the ones they already have. Their overall confidence increases and they have something to look forward to if they generally don't like school a lot. It also keeps them safe one afternoon when otherwise they may roam the streets.
So, if anybody wants to come and join us Thursday afternoons, you are welcome. I even provide biscuits or sweets sometimes.
My friends used to have their teenaged son's friends over all the time to play a game like that - in the US it's based on Dungeons and Dragons. But these kids made their own worlds, their own rules, everything! It's exactly like what you are talking about. How very cool!
