Warhammer Fantasy/40K and table top gaming

Never seen one of these yet so we use this topic to discuss table top games from the mainstream warhammer fantasy/40k to the obscure rpg's. Beyblade as a hobby has fell out of favor with me recently and I'm starting the steady progresion back into 40K after considering a few other games like warmachine and kings of war. I first started wiith space hulk when I was 10 and finally stopped 40K when I was 15 in favor of beyblade and my gcse's. A game of 40k or other similar systems can last the same length of a beyblade tournament at the "pro" level but maybe I just like it because the whole building, converting and scratch building like a type of stress relief after a long day at the tax office. So who else here has or played table top games/RPGs or what do you think of them genrally?
