Games workshop have been rereleasing their games since the 1980s and theyve gone through a number of lore and aesthetic revisions since then. Some sides such as the rines have changed little over the decades, others quite a bit.
Necrons are a relativly young side, i remember them being first introduced in the late 1990s. They had little to no back story then, and thats sort of what made them interesting. I havnt played any gw game for about 6 years or so so i dont realy know how theyve developed.
rarrrrr we are scary
ive seen the more modern models and theyve got flying pryamids n stuff now i think
The tyranids have alawys been based on the aliens architype, just like th zurg in starcraft (and the aliens in 60% of sciencefiction). However aesthetically they look much more like the aliens from Fox (R) films now than they used to imo.
Orks also used to be quite different although theyve improved orks aesthtics alot over time imo
couldnt find an actual ork, but if uve seen any of their post 2000 vehicals u get the idea
in my view both in 40k and regular wh gamesworkshop ran out of decent ideas for lore about a decade ago
ive still got quite a few models im trying to get rid off. Any UK bay12s pm me ur postal and ill send u models for free. If ur abroad ul have to find away of paying the postal costs.
