Going back on topic ---- I think Anthony's initial post probably sums up why I solo wargame now whilst in my youth (or when I had less grey hairs or is it more hairs that were coloured) I actively took part in clubs. I did go to the local club once last year but didn't get too much of a welcome, so never really had the drive to go back again.
The only downside I to solo wargaming is that my tactics are becoming too stereotyped so will be looking at ways of trying to involve others in defining the initial deployments and plans.
PS. Whilst having a dedicated desk to do the painting, I don't have a dedicated room (although that is the daydream) for fighting but can borrow the dining room table occasionally.
