After watching the DX9 vs. DX10 video of PT Boat, all I can say is that I would be very happy with the DX9 version.
Other than a few particles, the biggest difference I saw was that the DX10 looked a lot brighter. In fact, I thought the ships looked to clean. Neither side seemed to use Anti-Aliasing. The cables on both sides looked equally bad and I can live with the water splash effect of DX9 even though DX10 did look better, I just thought it as odd that neither showed wakes for the Torpedoes.
It was nice to read that you can get promoted and get more responsibility but I'm not sure if you play just 1 person (like in SH4) or do you play the sailor you are controlling (like in B-17, the Mighty Eighth) where each crewman can get promoted and decorated whether you control them or not.
I'd like to know if each person on your crew can earn decoration? Graphics are fine for me as long as there is a good career model.
And when are we going to get more then just the 6 basic hero medals. MicroProse had 8 Ribbons as well as the 6 Hero Medals (that 14 awards) way back in F-117a Stealth Fighter, B-17 TM8th had 13 awards (not all medals). I am feeling cheated in my navel careers

. I know the graphics keep getting better by why do the Decorations get shorter and shorter?
Even F-14 Tomcat (back on the C=128) had a Demotion video where your Commanding Officer would rip your Wings right off your uniform if you were bad enough. Where is "that" kind of detail now? It's al about the Graphics & Flying etc... now, not the players hard work.
