Several things contributed to me abandoning the game:
- My roommate who was working on it with me moved out, and without that excitement feedback-loop, my interest waned.
- I got a new job with a longer commute and hours, so I have less available time.
- I've slowly lost interest in Angband and other roguelikes. They've still got a hook in me at some level, so I may return, but most likely as a passive consumer rather than a project leader.
- My design-fever is better satisfied by projects I can complete by myself (rather than relying so heavily on others to do what I can't), such as my Adventure Time TCG (AdventureTCG.blogspot.com).
Also, I am still a huge fan of My Little Pony: Friendship is Magic and I'll try to use my passion for creating games to entertain the MLP community in some way again soon.
