Hey Sand Marauder,
I wish I could run you through a game on Mondays but I keep my 2 year old daughter on Monday evenings. Tuesdays at the shop are a bit of a different beast also, because the game area stays open to 10PM or 11 PM, well past when the shop closes. On other days, when the shop closes the gaming area closes too.
40k and Warhammer are great games. Let us know if we can offer you any helpful bits of advice!
Welcome to the forum!
