I bought SH 4 when it came out, (2007) and it's still on the same external HDD.
We use to play SH 3 at work and brag to each other about our prowess with our U Boats, but when SH4 came out it had moved up a gear and was a natural progression and became the pinnacle of pure simulated Submarines.
It had a wide screen, better graphics, a more intricate battle area, nasty opponents and I got to play the good guy, instead of the enemy.
I was disappointed when the update 1.5 turned out to be more U boats. It could so easily have been RN subs, which were very active in the Pacific.
TMO is my mod of choice and it never goes wrong.
The base and U boat update is available on Steam.
