Space quest, LSL and police quest series are some of my very favourite adventure games. The humour in LSL and Space Quest was very much my cup of tea.
I also loved Zak, Maniac Mansion, Indy adventure and the monkey island series.
Besides Sierra's police quest I could not play an adventure game without humour in it. So I never got into Kings Quest, Manhunter or even the serious lucasarts adventures.
