I personally love the Bryce interface. It's an easy, out of the box--no instructions needed--userfriendly interface. I demonstrated to the computer teachers how easy Bryce was to use (as some of our high school students are not as computer savy as others) and the school bought 5 copies. I am planing on using Bryce for the graphics and animations for my computer game (along with some posers stuff of course). i just tried the demo of Mojo World, and have now descided to find and read the documentation, because i found it (mojo world) very complicated. It is not user friendly (although this might change after I read the manual) I have been using Bryce since the demo of version 2 came out. I have used Bryce 2 to create a 6 minute film for my grade 12 history project (roughly 80 + hours of frame by frame shots) and Bryce 5 to create a 2 minute WWI film for a multimedia cd (a work in progress) on the history of flight. I plan on spending the $550 Canadian to purchase a new version of Bryce (so long as my computer can run it), but I do not want Bryce to loose it's simple out of the box ease of use. If the interface changes to incorporate new features--fine, but if i have to spend days reading the manual to create a simple scene...then i will be angry. Please remember: Bryce is an amazing program that can do Great things, but was made for simple people. Thank you for your time. Sincerely, David :)
