Besides the nice looking graphics and interiors model, I didn't really like anything else about SH5 in its current stage. The UI is what bugs me the most, it looks like a Windows Aero interface, to me that destroys all the immersion that you're commanding a 1940's submarine. SH3's old-looking maps, worn sheets of paper, buttons, authentic looking gauges and dials, logbook and messages with old typewriter fonts, etc all go with the game's theme and improve the game's immersion. It helps the feel that you're commanding an old U-boat not surfing a fancy website or using Windows 7 gadgets in 2010,

but to each his own!
