I miss the clunky MKII and it'd be great to get some late war model boats. But, like you I played SH3 for years and finally downloaded SH5. It's a very beautiful game and I found the relative cartoonyness of SH3 impossible to go back to. I upgraded my PC to accomodate SH5 eventually. But it's quite funny that 90 percent of my in game time is spent staring at icons on the nav map.
However, every now and then I take a stroll through the boat or go and stand on the prow and watch the foam or the ocean or the sunset and it's well worth it.
Another thing I'd love to have from SH3 is repair management and crew management. Both are very vague in SH5. You're never quite clear what repairs (if any) are going on and the crew are anonymous except for the unchanging officers.
The stock game sucks, TWOs is an infinite world of detail if you want it.
