It takes ages to load when you've died or between cut scenes.
When you press resume if you die it doesn't take you to your last save point but to the computers.
I don't like the fact you can't upgrade individual armour or weapons.
The characters aren't as charismatic as the first which means I had no interest in developing them.
AI characters are poor in fights as most of the time they run straight at the enemy without seeking cover so you constantly have to give direction.
To get minerals for upgrades you have to scan worlds which takes far to long. Prefer the old way of doing it. Seems a little unnecessary to add this to the game.
This was just a few of the reasons why I decided to get rid of it.
I got it for £17.95 from a deal I posted a few weeks agohttp://www.hotukdeals.com/item/589183/mass-effect-2-ghostbusters-xbox-360
