well, the quality of the gw minis is very, very good. itīs a question, of course, if you like skulls, purity seals, statues or gothic stuff.. (batman, anyone?)
the warzone stuff is far more... "retro".. most figs are bad/strange, honestly.. (slaughtermaster

, taking a ****)
of course, many of the new troops where very nice, but thats only very few.. LI, HI, Blitzers, brotherhood troopers, and some others, but far not all,
like jaegers, shock troops or hussars are pritty bad, in my eye...
but the figs ARE the reason to like the game, beside the fluff, at least for me (even though I was a little disappointed by the assault marienes, when I saw them... the "fullback" is taken too litteraly...
@fluff: what I really like is that humanity is fighting because they are corrupted by the dark symmetry into exeggerated pride/hate/etc.
in gw, there regulary the "sacrifice" of your troops is highlightet (ritus exterminatus, eg.) asl well as execution/transformation of soldiers, who only slightly commited "heresy" or insubordinace..
it is the religiouse fanatic smell I donīt like.. your officer does not put you to war trial, he kills you for not beeing a total obidient servant to him, and in the end to the emperor-god.. (who "eats" 100ets of voluntier-psionics to survive).
everything is too-- one wayed:
the orcs destroy always, no civilization -> genetic coded knowlage -> pure battlerace -> the only reaction to them is killing them
the necrons come, kill, go -> the only reaction to them is killing them
elder: attack because they must (to change flow of events)-> humans donīt understand -> the only reaction to them is killing them
(as well, the space-mariens think: aliens->the only reaction to them is killing them)
Dark elder: super evil -> the only reaction to them is killing them
in summary, the game follows this mechanism:
the individual needs to sacrifice himself (tau/elder: greater good/flow of fate, orcs: donīt care death, want kill, SM: fanatic, self sacrificing,...)
the solution is destruction, like ritus exterminatus, or general eradiction
the means: whats most effective: no humanity remains, everything goes. there is no mercy, even to your own people (servitor, anyone?)
and that all is simply not so great... definitivly less appeling than a colonized solar system with corps/factions who function normaly, and only sometimes start war, but at a faaaar lesser extremistic style than the 40k factions..
