Don't have a lot of favorite Adventure freebies... most of the freeware stuff I play is somewhat action-related. Some of the best two-player experiences I've had come from freeware/shareware games.
If I have to pick an adventure game, I guess it'd be... Ignac. And Ignac 2 will most definately go high on my list. I don't know.. I guess I just like high production value.
EDIT: Igor changed to Ignac.. Stupid me.
