Anniversary for me. Only played the original Europe and Pacific once each as my buddy has them and after we played them the two 1940’s came out. I liked the 12 IPC thing. In Pacific I liked the round one defenders suck rule. Just got Guadalcanal and D-Day but only played Guadalcanal once and not D-Day. Global is great but too long. Havent played the 40 games separate since Europe 40 came out and dont think i will. Bulge is OK but I need to play it more to say whether I like it or not.
Anniversary is great for all the reasons Garg said.
