<div>Mods developed for the Q3 engine used to be one thing. No engine licensing applied for anyone creating even a total conversion mod.</div>
<div> </div>
<div>But I was told years ago when I was interested in licensing the Q3 engine for a project a few friends and I were doing, we asked a bunch of questions about what actually fell under the "Need a license terms" and I was originally told that any game being offered as a whole built on top of the q3 engine or any deriv still required a license. It's also stated here, <a href="http://www.idsoftware.com/business/technology/techlicense.php">http://www.idsoftware.com/business/technology/techlicense.php</a></div>
<div> </div>
<div>But what I was told would mean that Tremulous, World of Padman, Urban Terror and so on would still need a valid Q3 Engine License. When you think about it, those are all games built on top of the Quake 3 engine or ioQuake3 but it is still the Q3 engine. I'm guessing ID doesn't much care because they don't outright make money off of them. But still, years ago, any game being released whether free or not still required a license. </div>
<div> </div>
<div>But as I mentioned, I guess ID has a different take now of free games as opposed to what their Q3 Engine Licensing states.</div>
<div> </div>
<div>Just my thoughts on this,</div>
