1.000.000 $ or € rig can fly you to the moon, but still isn't enough for SH5 if you don't have the proper internet connection ...
Long ago I discovered that past the novelty of the first months I had actually not much interest in SH5, and I'm more than happy to live with Sh3/Sh4 for my submarine needs. Well modded they still rock, and are flexible enough to allow me to tinker and make a GUI to my liking without learning Python
Sh5 is OK for anyone who really wants it. Me ... I'm too old and used to SH3/4 to move on.
