I may be more tolerant of some problems that delay products, even for a very long time than others (and I understand why some others are less tolerant here); specifically medical and related problems can just be a thing, especially with one-man-band operations, and as long as I have the sense that the creator is trying to stay in contact and move forward as he can, I'll accept a lot of delay. As a specific example, the author of This Defiant Earth (an RPG to emulate 50's SF movies, a particular love of mine) had a number of medical and (related) occupational problems that delayed the product a lot, but he kept in contact with us the whole time, and it did come out, albeit really late; I didn't fault this though I'd have liked it earlier.
