^ All I can say is wow, GWX Player, That is quite a description and dissertation. It sounds like you have a great deal of experience with all things, Sub Simulations.
You will fit in well with Subsim.
I only recently, got back into playing SH3 with GWX , with the great assistance of blackswan40. After conferring with blackswan, we decided my early version of SH3 on DVD had / has Starforce ( DRM ) on it. I ran the Starforce removal tool and concluded that either my Starforce removal tool was corrupted or I ran it incorrectly. Like Blackswan and others, you may end up as one of our technical guru's or go to guys.
A number of members here, including JimBuna, who welcomed you as well, have said publicly, that they prefer and enjoy GWX as well. Others like @TheBerbster have said they like Silent Hunter 5. RockinRobbins and others have worked diligently on FOTRS or Fall Of The Rising Sun to add to Silent Hunter 4, Wolves of the Pacific. You might want to look for them and give them a go since Covid-19 have essentially made cave dwellers of a lot of us.
As for me, I was driving my older model Chevy Camaro on a nice day back from a meeting when it spun a bearing in the engine. Up to that point, it was driving beautifully. I still have a lot of oil pressure so I doubt I lost all of the main bearings. Still, the engine will need all of the bearings replaced and most certainly, crankshaft servicing or possible replacement. I planned on replacement of the cam, main and rod bearings, head rebuild and if needed, boring out the cylinders in addition to a cam replacement and high end roller timing chain set. I also found a high end, all aluminum 4 row radiator I plan to install once the new engine is in.
I am in the process of acquiring 2 other engines with their transmissions either to rebuild or as a source of spare parts. If any of them are in better shape than my engine, I will install one of them after a proper inspection and servicing. This may well end up a winter project or I may at least start rebuilding the new donor engine(s) during the Covid distancing. I may detail the rebuilding process with pictures if there is any interest. I also found a Ram Air hood and setup so paint matching of the new hood is in the future too.
I have to start putting together the funding for everything as well. I started selling a number of items including automotive related parts and equipment to pay for everything.
It's always something. Stay safe with the Covid-19 viruses out there.
