KoA wasn't that great for me, and I know I'm far from singular in that opinion.
I got Dead Kell, but not Naros DLCs, and wish I hadn't honestly. The game was fun for maybe 7 hours then with the exception of maybe 2 bosses its really easy and really repetitive.
I played as a Champion or whatever the warrior/mage hybrid was because I hated pure warrior since I never used the skills and pure mage as I could just cast meteor and thunderstorm to kill everything in under 6 seconds for the entire game.
Finesse was not my thing although its what I started out as. I never really used any of the non buff skills and I grew tired of the crap damage that I was doing with melee and the crap aiming I was left with once I got scattershot for my bow.
In the end I had a tank that used hammers and chakrams and whenever I grew bored of combat I just used thunderstorm from inside my blue safety bubble.
One thing that was furthest from my mind the entire time I played it was the lore and the characters. I didn't care in the slightest, they were completely generic and unimpressive. As a matter of fact I've gone from complete indifference regarding Salvatore's works to actively wishing to avoid them now. McFarlane has never been my go to guy for art style either.
I bring this up because I imagine that the 2 things that will definitely carry over to the MMO will be the established lore and the art style. I've actually read all the lore right before the game came out, and it amounted to zero relevance in the actual game of course.
I've also found that the majority of the detractors of the game share the sentiment that the game is too easy, but if you bar that reason for disliking it they more often than not cite that the story and world at large are just not at all enthralling.
Which for an action rpg is bad business, when you have boring easy combat AND people don't care for your world you've created.
I'm sure I'm not the only one that thinks that Rhode Island was pretty ignorant of the realities of development hell, and took ridiculous liberties with taxpayer money for what amounts to a mediocre game that sold as such and the promise of an MMO in the same universe (only thousands of years in the future) is poor comfort.
Seriously why in the hell did they feel the need to LURE a non-established game company with boatloads of money to settle in their state based upon a track record of zero games made? Correct me if I'm wrong about it being their first game, but isn't that like bribing an author with millions to write their first book in your hometown?
Now, "mysteriously" they can't pay back the money despite "good" sales of KoA. I with that they could just cut their losses and stop working on Project C, because the amount of pending litigation for defrauding the state of RI in a year or so when said MMO fails miserably due to a complete lack of anyone giving a shit is gonna cost them much more.
