Irrlicht Engine

This is a rather silly question...ALL games made with Irrlicht should be promoted! But a library gets WAY more visibility with commercial or non-free applications than freebie applications. do you think so? maybe some developers know, but the users? at least when i checked most of the project pages...

i looked through the screenshots section and found only non-free games....

are there any free (as in freedom) games using irrlicht?

if yes, where can i find them, why are they not promoted seperately and why do you promote the non-free games at all?

thanks and greetings
