I'm a long time user of Torque, from the pre-v12 days and I still use it. But recently I also started using Ogre for some other projects with different requirements. Man its fun! Torque is such a big codebase and really needs a severe refactor (thats ongoing). Ogre is still big, but as its mostly libs and dlls and whatnot it is a lot easier conceptually and actually is easier for my students to get something visually pleasing with (might not do anything useful, but at least its motivating to see the fruits of your labour). I just find it fun to be able to get in there and literally code from the basics again (I'm used to code+script and lots of other issues now). I'm just going to get my traditional object+components+messages framework going and I should be set for a few little AI demos. Fun!!!
