My preference is for replicating as well.
A dream for me would be to reproduce the USAF Museum in Dayton (indoors and out) in 1/72! (If only I had all the time and all the money I needed...)
Now, if I were a fighter modeler, I'd be EXTREMELY interested in the large scales, like 1/32 (oooh - a 1/24 Spitfire sounds, well, orgasmic!).
As stated in seperate note in this thread, I see exciting growth in the larger scales, which is great news for the likes of us who are aging quickly. Again, even thogh my subject is bombers, a FULL set of the Century Series fighters sitting on the shelf would be impressive indeed!
As a side note, I have a resin 1/144 Zeppelin Staaken R.VI kit sitting in front of me. When I bought it (sight unseen), I was thinking only about wingspan - the thought process imaginged it to be similar in size to a 1/72 Gotha. Which is true - for the wingspan. But the details are TEENY. There's no way I can build this without a magnifier (i.e., the box is going back on the shelf)... I'm not a model railroader, but it's been something that I've been interested in for MANY years (I just never seemed to have the coincident time or space.) But I equate the model scale popularity/presence/growth/and fall to the railroad scales:
1/144-. == Z For those who want alot but don't have much space (I choose Z instead of N, because N has quite of bit of detail - in spite of its small size - whereas Z and 1/144 doesn't)1/72. == HO Availability, Low Expense, High Popularity (The HO "IRS on Fire" Building is a personal favorite)
1/48. == O. Popularity rising (once again). Aging hobbiests w/ money.1/32+. == G. Similar rationale to 1/48
The odd thing - IMO - is that the larger you get (above HO) in the model railroad arena, the LESS details there are (which is a real turn-off for me.) But I guess this is because of a more "toy" rather than "model" factor.
It's difficult for me to understand a desire for 1/144 and smaller (as well as Z), whereas it's easy to understand the preference for 1/72 and HO as a compromise - do everything - scale. But the large scales, where you can get fine detailing is truly exciting for replication.
