Epic Armageddon is a fair game, and there are certainly other rules available, but I do enjoy gaming at 6mm scale and since these are minis used with EA, I'll stick with that for now. It really gives a true feeling of a battle on the tabletop. No one I know around my area plays Epic, so for the time being, this is just a hobby project. Like all things GW, it is not cheap (overpriced would be the correct term), but every single piece of Epic I am using I did not get from GW directly. eBay and trades on gaming sites are the way to go. I spent less than $50 on this whole collection (not including postage for trades I made). I don't think I want to know how much this would have cost if I got it directly from the evil empire.
I keep telling myself that I am going to do some Imperial Guard or Orks next, but that's some time off, so we'll see how this goes and worry about what's next when that time comes.
