Thanks a lot for your replies so far and for the advices.
I know that most of my questions are gonna be extremely subjective, but if you can give me an opinion also in that department I'd be extremely grateful, even just to have an idea of what people on such a serious sim community think.
-When you play a naval/sub sim, after hours and hours of ambushing convoys and trying to stay stealth, what tactical aspect of this sort of fight keep your interest alive even after a long time?
-And when you play a flight sim, after hours and hours of battles in the skies, trying to get better shoot position and avoiding getting overwhelmed by other planes, what tactical aspect of this sort of fight keep you r interst alive even after a long time?
Thanks and tx for the warm welcome!
