As much 'fun' as developing enterprise java applications with Maven is, I would like to think that developing games with Maven would be even better :)
I'm hoping to convince the jMonkeyEngine project to let me mavenize their project, and in the process create a game archetype supporting 3d acceleration, sound, input, etc. I think it would be great to get a game-dev environment up and running with one maven command, as all the existing tutorials are complex and error prone. I thought I'd mention it on this list to see if there's any interest in such a project, or if anyone has tried anything like it so far.
