only reason it's so easy on CA as it is now is due to the fact there's so many source codes for old lithtech games floating around the net
I have the source for the following lithtech games complete and compilable
NOLF2
AVP2: HD
Contract Jack (Playstation 2 source though... might come in handy later)
FEAR
FEAR 2
commando: You're probably the best non-coder coder I know LOL
