That's just a little difficult for me right now. Since I'm in a German squadron, unless they let us fly captured examples, or unless the devs put the Siemens-Schuckert D I into the game, soon.
But, personally, I've always found the early war machines to be the most intriguing of the lot. Most WWI flight sims (computer and table top) pay too much attention to the middle to late war period and tend to ignore the early war stuff. And even though it was included in one of the first WWI air combat games, "Richthofen's War" by the late, great Avalon Hill, it was not really given it's due. That game pretty well generalized many of the planes in the war. Oh, hell, it generalized them all. But it was a start, at least for 1972.
FITS, or Fight In the skies (now called Dawn Patrol) also avoided the early war stuff. But since the author of that game readily admits he was inspired by "The Blue Max" I suppose it's understandable. Still, I've always liked the early war stuff.
One other thing I've noticed, in RB3D, if I was playing an early game (made possible by the people who created the Western Front patch) with 9 victories, I'd likely be up for the Blue Max medal. I don't know how they did it in the game, if it was already hard wired into RB3D or if the WF patch guys managed to make it possible, but I do know in "real life" the first Pour le'Merit medals were given out at around 8 victories, and it went up from there. Took the red baron 16 to get his. And yes, 20 at some later point. And as we all know, with paperwork slowing stuff down, some didn't receive their medal until they''d had even more victories. Some didn't receive it at all, if they were killed or captured. Seems the Imperial German gov't didn't like giving out medals to those "too careless" to get themselves killed or captured. I sure hope that attitude has changed.
What gets me, in this age of computers, with rumors of going "paperless" seems to me, there's more paperwork involved in various things now, than ever before. Progress, ain't it great.
