I'm not an SH5 player....but this thread caught my eye.
Looks like this guy needs a good dose of SH3+GWX3+SH3 Commander stat!
Seriously though. If you are into U-boats, you can't miss GWX. It's the best U-boat sim out there.
Also, everybody has a game that they hate in the sim Genre... I can't stand Train Simulators. I found MS Train Simulator in the basement and had about 10 minutes of fun just crashing...then I realized....TRAINS REALLY SUCK! Some people have tons of fun with it...but putting along at 40 mph with a mile of lumber behind me for a couple of hours just isn't my thing.
I'm at home in submarines and aircraft. That's about as far as I go with vehicle sims. There's the odd surface ship that I play...but subs and planes is the way to go. Just my opinion though.
