I find Men of War to be the best in the series, I find it a big step up from faces of war, and I actually feel it's better than the newer Assault Squad games.
it has a story albeit its read by someone who sounds like a history teacher, and some of the voice acting is pretty laughable, but this game has realistic physics, and a great ballistic system making tank, and gun duels to be very exciting, and stressful! Watching your tank rounds pinging off of a Panzer's armor is pretty scary, and Angles and armor thickness play a part in it too. I love that ♥♥♥♥.
The difficulty, well...this series is known for it's difficulty and long missions, and I can easily say this is one of the hardest strategy games of the Real Time non base building type, the AI is exciting to play agaisnt.
The graphics are not the best, but with some of the newer features on graphics cards, this game can be forced to look very nice,
very advanced controls (you can even control your units like a shooter) and a fast (but scalable) pace
An incredibly underrated game, from an awesome series.
Many compare it to COH but Men of War deserves some credit in the fact that they cover a wide range of weapons, units, and vehicles, with a much more advanced ballistic system, and a much more advanced control scheme,
they also cover missions and scenarios not seen in other game along with it's varied objectives that bounce you back and forth across the map it makes for a pretty exciting game.
Much more than your average skirmish the computer war game
