Though Black Mesa deserves a lot of the praise it has been getting so far on this thread, no course is perfect, and I did have some mild reservations about the course.
As enthusiastic as I was about Black Mesa after my first two plays, I did wonder how playable it is for everyone. And not just mid- to high-handicappers either. I think that if a significant tournament were held there (USGA Public Links or NM State Am, let's say), then the Tournament Committee would have quite a task on their hands to avoid 6 hour rounds unless they had spotters on at least a dozen holes.
During the two windy rounds I played, there were some holes (#2 into the wind, #10 in a left-to-right wind, #13 into the wind, #16 in a right-to-left-wind) where only a slightly missed shot could easily finish in the desert. And once in the desert, it usually takes a very good shot just to get the ball back in play, and I could see guys staying in the desert for a while.
Sometimes I'll play a course and think "This reminds me why the game of golf was match play for the first 400 years!" And in light of that I am more lenient on courses that others would label as "too penal". (Personally I think that if golf were still strictly a match play game, you'd see a lot more bold and daring things in GCA.) I see no reason why two mid- to high-handicappers couldn't have a fun match at Black Mesa, but I could them struggling to post a score if the wind blows.
But the same could be said for truly great courses like Pine Valley, Prairie Dunes, Muirfield, etc.
In the end, right or wrong, this may be part of the reason that Black Mesa isn't regarded as highly as courses like Pacific Dunes--there are a few more places at Black Mesa where the player can "run out of room", especially in the wind. But I think the course more than makes up for that in other areas, especially the routing and a great set of greens, and so overall I still regard it as an excellent and enjoyable course.
