I came up with the idea to do a harvest moon / rune factory style roguelike. It's in early development, but I've already had a ton of interest and a few contributors right off the bat.
If you'd like to help or want to test, check out the github page at
https://github.com/essial/harvest-rogue.
Currently, it builds on mac and linux pretty easily. Windows builds will come next week unless someone decides to port it earlier.
I'm trying to get as much feedback as early as possible to help ensurue the game is fun by the time it is completed. We also have a chat room at
https://gitter.im/essial/harvest-rogue as well.
