Games Workshop is probably best known for their Warhammer miniatures game and its spinoffs, but actually they’ve been making games for decades, and used to have a line of more traditional paperboard counter wargames. For a kick you can download one of them, The Battle for Armegeddon and it’s supplement, and print it out yourself and play. The game got a good review on the Boardgamegeek, and it’s very tough to get ahold of on ebay. Go forth and conquer 😉
