Skaven,
I have been a long-time lurker/occasional poster for many years, and I always wondered where you went. I developed a very strong interest in roguelikes solely as a result of your posts back in the day - which seems so trivial compared to what you have endured. I hope things improve for you soon.
Although my troubles pale in comparison to yours, I have developed major hand and forearm troubles over the years. I have found that Dragon Naturally Speaking still allows me to play turn based games. Should you find your fortunes turn such that you have an opportunity to game but physical limitations hamper you, many roguelikes can be played using only your voice.
I wish you the best of luck!
