Flashpoint is an excellent cold war 'what if' game. Highly recommend if you're into hypothetical cold war games.
WITE just recently received a new update, it is a monster game if you play the full campaign! Fortunately, there are a number of smaller scenarios with the game, as well as DLCs that make the game approachable. I also have WITW which is another of the large games the Grigsby is noted for.
Pike & Shot is a game set back in the era of, well, pike & shot. P & S Campaigns is very easy to pick up and play and I have spent many hours with it. The battles are relatively small and many can be played in an evening.
There are a bunch of others, but without knowing what you're looking for, or what interests you I'll hold off.
You and the rest, you forgot the first rule of the fanatic: When you become obsessed with the enemy, you become the enemy.
