iarwain, have you ever considered releasing orx a little more frequently?
I ask because it has been quite awhile now since 1.3rc0 was released. If someone arrived from other pages doing engine research, they might take a quick glance and miss all the new stuff in SVN.
There are a few nice new features and module functions in the SVN and it would be a shame for someone to miss them because they did their evaluation with the release version instead.
Just an idea/suggestion that more frequent maintenance releases might be helpful for getting even more new users.
