I started off w/ Close Combat2: A bridge too far. It was a good armchair general game, realistic enough but not too hard to learn, I really liked it. Skipped CC3: The Russian Front and jumped straight to CC4: Battle of the Bulge, didn't like it, they added a lot of annoying features that makes the combats drag on and on, so I didn't really pay attention to CC5: Invasion Normandy at all. Let me know how it plays I'd be interested to know
