i was thinking about starting bfg, and I was wondering what is a good way to start this game, I play 40k necrons, but iv heard that crons have so much cheese that a grey knight would feel like a grot against them. So id probably go imperial navy, so how much £ would i be spending, where can i get a rulebook? Thankyou so much for your help. Also is it an easy game to grasp, like 40k? Im new to this hobby.
