Graphics aren't really on the list right now. Maybe some day in the (distant) future. My current graphical goal is experimenting with ASCII and how to best convey monster types to players. Overall I'm pretty happy with it right now, but even as soon as 0.3c I'm trying out some new colors and symbols.
Music & sound is an interesting one to ask because I had just stumbled upon the Rogue Bard! I don't want to guarantee music and sound, but I'd say they iare definitely more likely to make an appearance than true graphics are.
I'm definitely working on pulling more interesting stuff from the expanded universe. I've gone on a bit of Star Wars reading craze this year, including reading all of the Thrawn books. There are some really neat species in the EU that I think work great in an ASCII setting, because they don't really have a solid visual portrayal. Sure, there's been artistic interpretations of them, but nothing as rock solid as say, Wookies. Everybody knows what a Wookie looks like - not everybody knows what a Sluissi looks like, which I think is just fantastic for the imagination.
The current setting (Tatooine) either isn't permanent or isn't the only setting the game will ever know. I have two different ideas I'm considering for a real setting: invent a real dungeon with a Star Wars feel and just have an end goal. Or remove the singular dungeon and have the game flow (probably linearly) between different planets.
There's a distinct lack of a roadmap! My only true goal is to make a game I find fun and hope a few other people do too. I might consider writing up a roadmap after 0.3c/0.3d releases. The only issue I have with big roadmaps is, if you read the blog in full, you'll probably notice the game went from a bit of a dark fantasy setting to Star Wars, which is distinctively space opera. While I don't think I'll change the setting again, there's also mechanical things I like to change at seemingly random. For example, the move to a D6 system was largely unplanned but has been good for the game overall, I think.
