Playing with childrens' toys or trying to re-work historical events?
Well, you'll have your own ideas. The site below has a 'gamers' account of their own version of the assault on Merville.
The actual layout of the gaming table looks very similar to 1944-era recon photos of the battery and gives you an idea of what the attackers of 9 Para were facing, albeit very simplified (minus machine gun nests, mine fields, flooded areas etc.).
Nothing too exciting otherwise, but I suppose anything that keeps the memory of 9 Para at Merville alive can't be all bad.
