My first memory of SH3, was before any supermods.
It was daylight, no clouds, no rain, glassy calm seas, I was in a type 7, creeping along at 1/3d speed (i don't think i had any notion of specific knot speeds yet), silent running, i had 14 to 20 meters of water underneath my keel, and i was trying to sneak into scapa flow, through the front, since there was no other way in.
And then, as i peered through my periscope, i noticed this destroyer Waaaay off. I thought, "hes so far away, i should get by him no problem", ill just be reaaaalllly quiet.
Umm,, no, he made a beeline for me, at which point i remember saying, "WTF! OMG No freaking way!!" After he pounded me into the sea floor, i exited the game thoroughly pissed off, cursing, "BS! That was complete utter BS!" as i turned off my computer and stomped off.
A couple days later, i was back at it again.
