Great game, great story, high replay due to great toolset, but some poor gameplay and interface elements.
Also when you drag abilities down to your quickbar it just removes the old one it doesn't replace it and let you move the other to a new spot you have to find that spell item or ability and place it again. All in all the interface seems a tad clunky.
This could be because the game performs only marginally well. I can play Oblivion full out with custom modifications to really make it shine and it runs well this i have to cut down a lot of settings to get a decent frame rate. That may also be the reason my interface seems clunky. Although these short comings you can get use to or even modify in the future since the interface is modable like WoW's.
Now the game really shined for me once i turned off the AI on my characters forcing me to choose all there actions. This removes most of the AI issues people complained about but also makes each fight much more involved since you get to really lay out your plans on how your going to play each fight out. This worked for me it may not be everyones cup of tea but i enjoyed the game much more this way and play it on the hardcore rule set with it.
The story is great and most of the characters i like except the rogue an bard. I can do without either of them and never have them in my group just far to annoying but other than that the other characters are well voice acted and seem to add a bit to the already massive story.
And this game will keep you up many nights the first act took almost 20 hours for me.
Now after your finished with the main campaign there will soon be modules out so you can continue playing a variety of different games. I have bee messing around with the tool set and so far its quite robust. There is a steeper learning curve than the old one but if you dig yourself in you should be able to start creating some interesting modules.
So yes the game has some flaws are they show stoppers?? I don't think so they will frustrate ya for about an hour or two but then you will adjust. For all i know a mod may exist that fixes a lot of the interface issues. Even so the game offers hours of gameplay, a great story and a tool set that will make the online community for the game just go ballistic. Its a great game and i know i will be playing it for a very long time.
