My two cents:
- It looks practically identical to the FS2 HUD, but I think WC-ish adjustments look pretty cool. The changes made to the radar and target info section area nice touch.
- I don't think 640 is an option for playing this game; the only way to enjoy it would be at 1024. The HUD looks cluttered in the lower res. I know what people are going to say: "But it was cluttered in WC and WC2 and...". However, it was cluttered for a reason: immersion. Flying the Dralthi, with its claustrophobic cockpit, was supposed to make your feel uneasy. After all, you didn't have the option of ejecting. Same thing to a lesser extent with the Tarsus (or Orion, forget which). The low-res version is cluttered for no reason. Therefore, I'd recommend that later screenshots concentrate on just the hi-res version.
- I don't quite get the "customizability" of the HUD. Is it just going to be changing colors and brightness? If so, that's all I need. Flexibility in the HUD, being able to move around components, really won't make or break a game for me, just as long as the HUD is workable in the first place. After a couple of test flights, the interface should come back to me. (BTW, I never played FS2, although I played FS a long time ago.) Anything else is just icing on the cake.
- I would love to have the old days of sparks and wires coming from the console, cracked cockpit glass, or running through my damage displays to find "Comm system: Moderate damage". The 'uncertainty' that Delance mentioned was a fun element - except when the targeting went out before I could fire my torps. That ticked me off when I got through all those fighters just to...I digress.
Anyway, if it's going to take extra time on the order of months to come up with a workable alteration that provides that element (that is, if it can be done at all), it's not that big a deal. If you can make an interface that has some elements of WC(which it does) and is intuitive and enjoyable (I can't tell you that until I actually play the game), then you're fine in that department. Where I'd be spending the bulk of my time is ensuring the plot and missions are up to WC-standards. That's what will make or break the game.
