Hello TTLG,
I am a french videomaker-wannabe who recently produced a lenghty analysis of the game design of The Dark Project, and then a less appreciative one on Thief 4. Having browsed this forum for years for interesting discussions and juicy fan missions, I know this place has the best concentration of Thief enthusiasts on the net, probably including french ones, so I humbly submit these videos to their attention.
