I got the bug pretty bad, stopped buying gaming stuff a long time ago and gave most of my stuff away. Then I found Bolt Action a couple of weeks ago, when I was a kid we were using the old Tractics rules for 1/72 scale WWII miniatures and this brought me back to the good old days.

Far cheaper than 40K, you can find the stuff at a decent discount online. Have 1000 points of German Heer in the assembly process, got the boxed set for under a hundred shipped and that includes two vehicles. You can get the rule books in Hardcover, PDF or Kindle format too, ($10 a book via Kindle vs $20+ for hard copy) There are a ton of other sources for figures and models in 28MM (1/48 - 1/56 scale are acceptable too) too so you are not tied to a single source for your addiction. (No GW tax) Have paints on the way and will post pics after I get a squad or two painted up.
