Not that I'm bored with Nethack (I've been playing since 80s) but I was kinda hoping for new characters, quests, dungeon features etc. after the hiatus. 12 years in the making and all we get are bugfixes and cosmetic changes. I've been periodically checking their website for any updates for a long, long time.
OK, that sounds ungrateful and I'm not, but since the Monk character is the only one I've yet to ascend I was looking for more...challenges.
