*looks guiltily at the fresh painted bloodletters, and half painted daemonettes in front of his keyboard*
I have fond memories of reading the Rogue Trader rules/book when I was about 13, a friend at the time was very much into Rogue Trader and Bloodbowl at the time, and that got me interested.
I play it occasionally, mainly with a bunch of friends over the space of a long weekend (I think the youngest of us is about 25), I like the "fluff" and the painting is relaxing when it's going well (and a sure way to raise blood pressure when it isn't

).
I've actually got about 1200 points of (badly) painted tau, about 2000* points of unpainted tau, a largely unpainted Empire army and i'm currently painting a Daemon spearhead (the large box with the soulgrinder etc in it).
I'm actually finding that I'm able to do more with the models now than when I was young (I bought my first army [orcs] when i was about 15), but now have the time, space, money and transport options to actually play with friends.
I think that's very much true for the guys I play with, 3 of them have been playing together for years (and have a huge collection of models/books), but most of the others have either just started or restarted in the past few years.
Funnily enough most of us met due to PC gaming, most of them were in the same Counterstrike Clan as my brother circa 2000-02
*I tend to buy the models in the army/spearhead boxes due to the insane savings - iirc the £100rrp Tau army box had £140 worth of models, I bought two of those (the second one for about £80), same sort of thing with a Tau rapid insertion force set (needed more crisis suits and that worked out cheapest), and the Daemon big box, and empire box.
