Dungeons & Dragons. 4th Edition. Not, it must be said, my favourite thing - but nevertheless a good social event with my various pals. I seem to recall 1.Ed (or Basic) was more fun; certainly it was less balanced and involved more roleplaying and a lot less combat. Anyway, I've been gradually painting up some old Citadel and Ral Partha minis for it.
The chap on the left is Citadel's 'Wat' from 1985 and my first ever miniature - given to me by a Primary School friend at the time.
