Very bad! do not expect anything like Divine divinity as it is really buggy and the interface is quite stupid.
controls they tried to oversimplify the controls and instead they made it completely unworkable as there is not tab for your skills and you must assign all skills independantly on the your mouse buttons. Also various places look like mazes which go on and on and on with no real meaning. Furthermore everything is really buggy and to give you an example when you reload a few times the sound goes off and you have to restart the game...trust me you will have to because the game has a knack of instantly killing you (unseen traps or something special about the creatures which kill you like you are a bug when they do it)
Yet after all that i decided to still give it a chance and continue playing for divine divinity's sake with the possibility of improving both the plot and the gameplay which was quite boring for the first few hours.
However the killer blow is trading, make one small mistake and you are done for it... If you decide to play it never press enter while trading because if you press it at the wrong time everything could be traded with no money, that's what happened to me. Really i was loaded with stuff and traded them all for nothing. That was so frustrating that i uninstalled the game and made my cd's frisbies and watched them fly.
It is not worth buying...heck not even downloading it's a complete waste of time and money. Stick with your divine divinity memories (which was a great game) and do not try this abomination.
