Just read through this, found it a nice read. I think the one thing that is missing is some of us, me included, have an uncontrollable urge to just be different. Where 40k and FB were the "popular" games so we just couldn't play them. I was like that.
For me, D&D advanced started me off in 4th or 5th grade and through junior high with a bunch of friends, then magic the gathering but that became WAY too popular.
40K was what was playing everywhere at the day we stopped into the hobby shop and me and my brother split the cost of a large starter box for the game that came with a ruleset (I couldn't tell you the edition) a bunch of templates and some terrain. 2 small tact squads of marines and enough for 2 small elder infantry units. We were really blown away by the models and their look and we just spent every little dollar we could through highschool on that game. by the time my brother had a full space marine "army" and I NEARLY had a full orc waaagh! we had lost interest. in the way way way distant future, they should have something better than a gun to fight combat with American civil war tactics! and motorcycles?

? LOL we lost interest but thought, we need to finish our armies so we can actually play!!! we were slow to pick up models because of money.
perfect timing for warmaster to come into the scene. so for the same price as another Nob and a flame boy blister I picked up a chaos starter army and my brother got an empire starter army. We liked the models enough but most importantly, floored by the rules and the tactics inside the game. Finally we had formations and flanks and infantry support and Oh, the site of an entire army on the table with flags and banners and the terrain!!!! not to mention that scale is really quick to paint.
15 years later, its still the terrain and how much MORE you get on the table at the scale, the sight of it all should impress anyone if done up well. And yes, warmaster has great rules and was never very popular.
I still watch battle reports on youtube of all the FB and 40k games and it certainly has evolved and certainly looks amazing but I have no interest because I never see any tactics, just meet and greet battles to see who loses their biggest hitter first. Oh and another gripe, ha! the fact that you can completely gun down an entire mob of slugga boyz but the orc player got to choose the killed stand always irked me. Oh look, the one guy that stands taller than the rest and has the power claw that could kill us all in one turn and should be in everyones cross hairs is still standing! every time!!!
done griping, I took a leap of faith in picking up man o'war as well and have fell into a love almost hate relationship with that, despite it's unbalance (dwarf vs. chaos) it has lived up to my dreams with the ships!
