I agree that vector graphics would look good in this case - Some people still have smaller 1024x768 monitors that they would play the game on, others like myself have the newer, big 1920x1080 deal or such.
Given that there's a number of ways the GUI could be re-designed, I think we need to be clear on how the new design should really work first, and then I could work on putting it together.
- Do we use vector-based graphics? (I'd recommend "yes" as I think it would work much better. On my big screen, yes, up-scaled graphics DO look "clunky.")
- Do we go for a "solid" GUI like the one we have now, or something translucent, like the glowing HUD-type deal I was talking about?
- Should we have individual buttons for each soldier? (I personally favor "yes" here.)
- For icons (For example, showing crouching vs. standing, and others) should we use pics made from renders of actual models used in the game, which are then altered post-process to be made into a button? (Duo-tone would look cool, wire-frame render in monochrome might also work.)
- How much of the GUI should be drawn from graphics files vs. generated by code?
