Massive bugs makes it unplayable.
This days it's very hard to start a game and immediately notice bugs, only UBI brings you this joy.
The bugs are infinite and everywhere. You just CAN'T play this game as many features you need, just don't work.
The interface, playability and commands are horrible.
As many other Ubi games, they came out absolutely bugged and NEVER get fixed. You may wait for years for the patches.
For example Sturmovik 1946 has an incredible 119 patches, and is STILL bugged!
I bought Cliffs of Dover from ubi as well, and it's just unplayable, they are jokers!
Also the graphics are good, but they run way to slowly for its quality.
They make simulators that no one else dares, but they only make 80% of the program and release it without testing.
