Game developers are often notorious for seeming to ignore fan feedback, but there are definitely some companies which seem to go the extra mile. For the life of me I can’t remember the name, but I recall a story about a developer for an FPS game which received feedback from one player complaining about a particular map feature screwing up strategic play (a tree, I believe), and they removed it on his request. I found that pretty impressive.
What game developers do you think do the best job listening to their fans and building a relationship?
