Touching on that and the subject of uboats, the movie Das boot, Silent Hunter 3, modding etc, I had a moment of realization. That moment came when, after a long patrol in a Type 9C uboat in SH3, and felt relieved when i saw a swaztika flying on a ship near Lorient harbor. It occurred to me then, that i saw the Nazi flag as a flag of a friendly nation. I was as elated to see it, as i was the US flag. At that realization I wanted to slap myself upside the head. That was when my disillusionment began, I was throughly disgusted with myself and thought long and hard how I got to that point.
In my opinion, Das Boot cant hold a candle to The Thin Red Line. ( Full movie here) Best war movie ever made i think. A lot of the thoughts expressed in this movie mirrored my own from my own time in the military. It hit the nail on the head.And, yes, "Das Boot" is in my collection of war movies as it exemplifies better than most what I see in these movies.
SH4 never became popular..??
Comparatively to SH3, no it didn't.
