Recently I've been involved with another commercial game project, and I decided to implement it using
irrlicht and
irrklang, a process named
dogfooding. Now that the project is reaching its final milestone, I think it was a very good decision: The game was written in record time and had no technical bugs at all. Sound integration was extremely easy using irrklang, and irrEdit helped me editing levels without the need to change on line of code which was a life saver. Additionally, bitplanes additions to irrlichts gui and his font tool have proven to be extremely useful.
This was one of the few times where I personally used Irrlicht again for a commercial game project and I like the library we created even more after this, and became fond of
my own additions :). I don't think I will be allowed to reveal what game this actually is, but I'll ask the decision makers anyway, let's see.
