|Two sessions worth, which is a couple hours.|
There are other factors in the simple(ish) scheme beyond the sculpts. Since Warhammer Fantasy (henceforth WFB) revolves around blocks of troops, individuals don't stand out as much as they do in a "skirmish" game (using the term loosely) like 40k or Warmahordes, so there's less drive (for me) to paint all the bits. (Of course I am painting all the bits, with shading and highlighting no less, because there aren't many of them as discussed above.) There's also scale to consider. Small units start at 10, while the large blocks that center your line likely start at 40 and go up from there. With that many bodies, and so many of those bodies largely hidden from view, it's a poor use of time to paint each one to the fullest (says the guy doing just that). It's a different approach for a different game with a different aesthetic.
P.S. - Mere moments after I posted this, I headed over to Faeit 212 to catch up on GW news. What do I find? This blurb about a new edition of WFB and a starter set that includes Empire. A bit of good news/bad news there as I'm working up momentum for the long-delayed push into WFB but will now be a bit more reluctant to invest in the current iteration if there's a new one in the pipe, especially if it has Empire troops in the box. Of course these are just rumors, though his information is generally pretty reliable, and I suppose I could always just lean on EV's books for the duration of 8th...
