I don't particularly like 40K. I read the rules, but the price of the minitures to play the game was prohibitive. I rather see a nice near future hardcore sci fi CRPG.
Thats the beauty of it, you don't need the miniatures to play a crpg. No painting, no cutting, no super-glueing your fingers together...

Do yourself a favour and grab some of the old source books if you can, Rogue Trader, Slaves to Darkness, The Lost and the Damned etc.
