You are not wrong, there are as many extras for wargaming this scale as in the smaller, of course they are a bit more expensive, but the figures are actually around the same price as 28mm, and sometimes cheaper. My Conte plastics work out at a pound (GBP) each. Also, scratchbuilding terrain in this scale is easier and allows for more detailed work. As for rules I use a homemade variant of GW's Necromunda system, which works very well. I don't like my rules too complicated, and some large scale skirmish sets I have seen read like a military academy training manual. Simple is best for me.
