I'm sure at some point I'll be playing at 100% but, I think if you are to restrict yourself to just the stations the devs created in SH4, then it's an even more claustrophobic experience than the real thing! At least in reality, as ship's Capt, you were able to roam the entire sub at your perogative. I know a number of us 'end-users' would've liked to've seen the whole sub rendered, with the ability to 'free-roam'. That would've been more like 100% realism, but alas it wasn't meant to be. Well, at least I got my beloved transparent surface

. Perhaps SH6?
