Looking at the screenshots in the article, I actually liked the graphics in Avernum 3 and even Escape from the Pit, they seemed consistent and actually pretty well done if a bit simple. I understand the complaints about Queen's Wish. They're not necessarily bad, I don't mind a lot of the tiles, but something does seem off with it. That being said, I've seen far worse and if the gameplay's good then it doesn't seem like that big of a deal.

I've actually been tempted to buy Avadon the black fortress a few times. It keeps showing up on steam(after reading this I had to double check, for some reason I had a feeling it was one of his games), again i find the graphics to be appealing. I'm just not sure if i want to invest the time into an RPG right now.

It seems like an easy solution would be to allow the tiles in the game to be editable and let people make new ones if they're unhappy with the ones that ship with the game.
