In this forum I hear much talks about the death Jazz3D project.
I hope thats only in reference to the official Jazz3D project.... Im still trying to get a graphics card out to uganda to carry on work. However much paper work is being done !

As far as Jazz 2D or 3D ...its the question I set out to solve when I started my project. The entire premise was "would the jazz world and moreover it's style work in a 3D environment ?" so far the results are very promising. The hard part comes from the moves being dynamic enough. Jumping backwards in very hard to make fluid in 3D, in 2D you have a distant view of the action so you can predict and visualise where you intend to turn and land but in the brave world of 3D you can only see 90 degrees max of your world at any given time.
This obviously makes judging some moves very difficult.

The great thing about 3D obviously is ... ITS 3D. You can do some things you just can do in 2D and if you can still keep the speed and fluidity in there then you are onto a winner !

The hard thing is that in terms of building levels...3D is much harder than 2D... getting modelers who are willing to work on a free project and make large fun levels is the bane of my game-developing life.

So 2D or 3D ...still a very hard question...in the end it all comes down to whether you can get the style from the original into the new game.
