I had a very large high elf army back in the day and medium space wolf and eldar 40k armies.
My dad used to paint them to a very high standard.
He would get sick of mithril silver and space wolf grey, so I ended up with a number of blood bowl teams and necromunda gangs just so he had something different to paint.
I was never a big fan of actually playing warhammer or 40k though, Blood bowl was by far the best game.
I'm surprised people still play the table top given the costs these days, especially when you have some decent GW video games.
