I've considered giving up gaming as well. I took a month long break and I feel like that invigorated me somewhat: http://plus10damage.com/blog/2014/7/4/my-break-from-gaming
I feel it's something every one experiences at one time or another, and when you're constantly exposed to something, burnout is inevitable. Maybe try taking a small break rather than quitting all together. Or even better, do what I've started doing: limit the amount of time you play games each week. Cut back. It helps keep your passion alive whilst simultaneously making you more productive. A win/win imo.
Whatever the case is, it would be sad to see you go. Even if you do end up going on haiatus, please do drop in from time to time.
