Ahaha... I remember this, I used to play jaykin bacon source (even though it wasnt really source...) back in the day, I loved playing it single player as there were no servers.
As for the tf2 maps, Ive made one MvM, two ctf and one koth, most of which are pretty darn silly if I say so myself... They have some tweaks that need to be preformed before I can say they are finished but Im holding off on that later till I figure out how to open hammer again...
