The time period is actually pretty irrelevant - it is what you 'invest' in something.
I came to the hobby when I was well over 40 years old, in the late 90s when my two boys discovered Warhammer. Joining in with them and helping them with their armies, and making scenery led me to get my own army.
Then I became hooked and as my sporting life waned, tabletop gaming was my new hobby.
So I have had around 20 years of it and the Warhammer Fantasy world was the main 'glue' for most of that period - that is what you miss.
That loss is the disappointment.
You could walk into a gaming store or go to the Eurobash and other people there knew who Raukov or Todbringer were.
Hell I know lots of people who have had shorter marriages than that ............
............ and probably invested less in them.
What is also very frustrating is that now. today, we seem to have proper management back at GW, starting to do things the old way again, with them investing in the hobby to get sales.
Unfortunately it had to happen after they canned the Old World.
