Just completed this, thoughts below:
+Nice stylized graphics and setting, Paris looks good in places and I like the way the colour hue changes as you free different areas of the city from Nazi oppression.
+Horror stories about EA shutting off the servers earlier in the year didn't see to do me any harm, the game worked fine including nudity
+Interesting blend of Mafia and Assassin's Creed, although inferior to both.
+Characters and dialogue are generally strong
+Reasonable blend of action and stealth i.e. it doesn't force you down the stealth route, you can rambo most missions if you want to.
-Game runs in low resolution unless you set 60hz, incredibly shoddy and I only found out how to 'fix' it (i.e. change from 120hz to 60hz) by googling
-Annoyingly makes you holster weapons for no apparent reason in certain places (e.g. some checkpoints)
-Driving leaves a lot to be desired although this may be in part due to the era (same accusation could be directed at Mafia)
-Some graphical glitches especially when viewing things at a distance
-Respawning enemies, there is one mission where you have to assault Palais Royale and destroy buildings, Zeppelins etc, I couldn't figure out how to take out the Zeppelins at first so just progressed further down to take out other targets and try to find some dynamite then came back later, the baddies had respawned even on the sniper towers :/
-The map really sucks, even opening it from the menu you get some stupid tiny map that is unusuable so you need to click view full map, then when you get it out as soon as you zoom out to try and see WTF is going on it gets all messed up, the legend overlay doesn't scale properly so all the icons end up in the wrong place.
Overall I wasn't particularly impressed at the start of the game but once it gets in to its stride and developing the characters, it starts to shine. It was a pleasant surprise and reasonably original in terms of the setting too, there are plenty of WW2 games but not many dealing with the resistance.
