Yeah, there's not a list per se... the two little games I did, aquarius and circus quest have the source included... as for lsl reloaded, there should be a download link somewhere under the navigation which is a zip file of that rooms resources and you're right it's not really a tutorial, just sample code. if you aren't familiar with the events that occur in a room you probably won't go looking to see what's there. I'm not sure about all the others games and sources though.
* When I go through and unAGI our games page when agigames.com is up again, I will go ahead and add a checkbox for if source is included.
