Sorry to hear about your health issues. I hope the surgery improves things for you. Gaming when you are sick can definitely be difficult (and when you are not well, energy is often hard to come by). For the last two years I have been dealing with serious complications from crohns disease and it had a huge impact on my gaming. Earlier this year I blogged about gaming through illness (if you think it might be helpful feel free to check it out: http://thebedrockblog.blogspot.com/2012/03/gaming-through-illness.html).
I am also someone who doesn't play much D&D anymore. I used to play it a lot but now I prefer either a game like Harn (for more realism), or Savage Worlds (for cinematic stuff). I also play my own games, which are a pretty good blend of gritty and rules light. When different people in your group want to play different things it can be tricky to keep everyone happy. Best thing in my opinion is to have a frank discussion where everyone can freely give their opinion. You may be able to strike a compromise if you know what folks want. My own solution is to game with a few different groups.
I will check your blog out.
Between my back injury and the pain and worrying about money and paying the bills my hobbies have suffered. For one thing my patience is very thin I get frustrated very easily and the pain medication dulls my senses so it is hard to concentrate.
I think one of the biggest fears my players have is that all they know is DnD they are worried they don't have the time to learn a new system or the money to invest in a new system. Most of them are in their 40s and are set in their ways sure in their younger days they played different things.
It is not that DnD is going away my roomie will be still running her game though when it finishes she is switching to Pathfinder but they are fine with that. She runs adventure paths. And we have all enjoyed for the most part Age of Worms. So DnD will still be there.
I am the one who runs home brews and am finding that DnD just does not work for me for the most part.
