I was reading through this article about early 40k, it's a really interesting read and intersects a few ideas I've had over the last few months.
A few points...
I generally agree with the idea that GW has never given a good reason why they got rid of Squats as a faction, but I suspect it was easier to rebrand the "Space Elves" as Eldar (and now "Aeldari" to conceal that origin even further), while the "Space Dwarves" would be too hard to dissociate from their Dwarven heritage.
I miss the bad puns in GW character names. I miss a lot of that old 80s attitude, but I've moaned about that here on the blog a few times.
There have been so many missed opportunities by Games Workshop in the desire to simply sell more minis...again something I've moaned about a few times.
I really miss that early idea of a techno-fantasy battleground. I'd totally love to do a mixed 40k/Fantasy battle. It's a shame the games keep diverging further and further apart.
