What is IV missing...

[Rockin Robbins]

• Equipment malfunctions, especially electronics! 100% reliability can't be called simulation!
• Digital compass course under compass instead of rudder position!
• Steering by heading not direction of movement, both in forward and reverse.
• Map positional uncertainty, weighted by distance, target height and observing conditions for visual targets.
• Real ONI recognition manual not containing all targets in the game and as ambiguous as the real one
• Stadimeter adjustments: you should have to input the height of the deck, cabin top, funnel or mast you want to measure into the stadimeter and then take the sighting, just like the real sub. ONI manual should contain multiple height measurements for each target.
• Digital range readout on the radar
• Direct TDC input from radar and sonar for range and bearing
• Realistic diving behavior, varied by speed of submarine.
• Direct TDC to periscope connection as the real subs had. American subs COULD do Fast-90. SH4 ones cannot.
• Player control of ballast system. Just once I'd love to issue the command "Flood negative to the mark." Require trim dives to calibrate negative and incorporate specific gravity changes in the water to penalize not doing trim calibration dives.
• Digital input of depth and heading orders.

Yeah, there's more, but that's enough to make a game that's much better than we have.
