Entertaining, but has some flaws.
Many of the reviews on this site call out the slow frame rate and disgusting AI. The frame rate is about 1/2 as bad as most say, but it was very hard not to notice the stupidity of your foes. The pure lack of awareness of the Germans is without a doubt the biggest drawback of the game.
The story of Turning Point is interesting alternate history, and is worth your time. Another huge plus is just seeing the 3rd Reich's epic new fighting machines in action, and the landmarks of New York, London, and Washington D.C.
If you're a fan of history, like myself, then you'll enjoy this game.
If you're looking for some new and ground breaking game, look elsewhere.
Be sure, that the ratings given on this site judge this game a tad too highly.
