Back in high school me and a friend of mine managed to make a rather shortlived but fun adventure for few friends of ours. It was really hard work being a GM(my friend) so I helped him when he got overwhelmed by rules or our players' inpatient nature

I still harbour a lot of fun memories from back then. I recently tried to acquaint myself with 4th edition but somehow it didn't grab me and I am very reluctant to give it more of my time...
