Just caught a glimpse of this video showing AO's new graphics currently in the works and I was very surprised. I had heard awhile back they were planning a minor upgrade, but this appears to be much more than minor.
We had played the free version for a month and enjoyed ourselves well enough to pick up the expansions and subscribe. There are some really nice aspects to the game and definitely different from current offerings. But after a few months we hit some walls of frustration and moved on.
I still have a free account and it still has a place on my desktop. Will definitely be revisiting after the update.
