I decided to get a look at jME because I read that the community is big, responsive and supportive. I have just one concern : the last jME release seem to be the 0.10 which is more than 7 months old.
Does it mean that this great engine is slowly abandoned or should I not rely on release regularity, the night build being actively updated ?
Sorry I'm a bit late but consider to take a look at Xith3D, too. Progress went increasingly fast these last 10 months. Not saying jME is not as good or whatever but some people actually found Xith3D better for what they wanted (talked about the "cleanness" of the API..).
And I have mixed feelings about Mark's and Joshua's work at NCSoft, I find cool that they've been employed ("success of the open-source model") but on the other hand, and as they said themselves they "keep the best things [in jME] for themselves [understand:NCSoft]" so..
