An alternative grand strategic WWII game is Strategic Command - also has a demo - also pretty good, but has only the ETO as opposed to the world view of WaW. In terms of complexity/realism WaW is 1 step up from SC.
Having played all 3 of these games (WiF, WaW and SC) I would like to add that SC and WaW are fun games, but neither is very sophisticated. I guess the term is "beer and pretzels." I would agree with Sterckxe that WaW is astep up from SC, but not by much. If I was going to rate the 3 games on a 1-10 scales for complexity, SC would get a 1, WaW a 3 and WiF a 9. I would also like to add that I maintained interest in the two "beer and pretzel" games for a month or two. Then you figure out all the gamey strategies. If you don't apply those gamey strategies you get slaughtered when playing PBEM. I've been playing WiF for 3 years and I'm only beginning to scratch the surface in appreciating the strategy. Of course a typical game of WiF takes about 100 hours to play. If you have the time to learn and play WiF, this is the WWII grand strategy game to play.
You can't fight in here...this is the war room!
