The Hype for this game was on par with what EA's marketing team does for most of their games. Overall the game is dull. A major aspect of the game, the ability to fly "Iron Man" style, is limited by the overheating effect. This mechanic needs to go but has been so integrated into the combat of the game removing it would break the enemy's ability to force you to the ground and rush you with sheer numbers.
The AI in the game is far from challenging on any difficulty. The change to difficulty only affects the amount of damage given/taken.
The reward system for any aspect of the game, even after the "fixes" and updates, is still meh at best. Getting a higher-level version of the same items gets dull fast. The bonuses applied by the various items are hardly even noticed during gameplay. It's sad really, and pointless.
With so many other options available for this type of game (loot shooter), my advice is to go elsewhere.
