My failing is that I hate playing a wargame with unpainted miniatures. So, I painted an entire North Africa themed Italian army for Flames of War before putting them on the table. Played my first game of Flames of War and thought “What a stupid game” and never used them again.
Might I direct you towards Battlegroup? No silly, gimmicky national characteristic and the like special rules, no constant rule revisions and version updates, no Napoleonic tactics, no WW40k, no seperate national army books, certified non-Wehraboo ruleset, recognises and rewards the use of historic WWII tactics, allows for use of various combat support elements like logistics, engineers, medical, etc, lively and engaging FB group (if you're into that) with direct input from the writers, played by all the best people. Probably.
