An interesting article on denofgeek.com appeared this morning:

For me it's probably playing Space Hulk, or mordhiem. Being able to play both games at home or a friends house easily was a massive bonus! Playing mordhiem till the early hours is definitely a favourite past time. All the terrain you need in a box with all the miniatures was such a great starting point. Levelling up your warband and creating stories for each character as the campaign evolved over a few games in an evening was pure joy.
So Dakkadakka do
Rpg's offer the best geek night in?
What would your geek night in involve?
