One of the early games in my collection was the Avalon Hill game of the American Revolution, 1776. The game was released in 1976 for
Orages a L’Est actually has two games set in 1944, Turda, featuring a joint German-Hungarian counterattack against the Soviets and the Romanians near that town in Transylvania, and Tali-Ihantala in Finland. I picked Turda because it had a flat, featureless map, and, how many times can you say 1944 joint German-Hungarian counterattack?
Mind you, this is not a simple game. At its base, it is just move and then a combat CRT based on odds, but with chrome.
