Very interesting to hear his views on the old systems. It's interesting for me to hear how he thought 40k became such a mess with all the additional stuff. I'm giving serious thought to taking a break from fantasy once my pre 90s empire army is finished (nearly there) and finally painting my rouge trader era 40k stuff.
I have most of the additional books but only ever used the ork books in the past (way way back)
I'm thinking of setting up a game, but only using the core rulebook, it will be imperial army vs judge dread perps and muteis so no need for any special lists
