You probably heard it before elsewhere, but I was waiting for some actual developments to occur instead of making yet another "yay! source release!!!" blog entry ;)
Anyways... the kind people over at id software have decided to release the source code of this two awesome games under the GPLv3.
The guys behind the engine improvements of Quake3, IoQuake3 have already a source repository running and you can expect them to merge all the nice stuff from their Quake3 version into it soon (like in-game VOIP and 3D sound).
XReal goes Wolf:ETNot really surprising news (due to the long silence of the project), but XReal the game is dead :( But don't worry too much since the main developer will now focus on getting all the awesome engine features into their version of Wolf:ET!
They even got a nice (but older) video along with that announcement showing what kind of ET like environments are possible with XReal:
Last but now least I have asked the guys behind the XReal powered WW2 FPS featured in the last blog post, if the ET source release would effect their plans...check the thread on their message-boards here. Would be for sure awesome if they would decide to make a super awesome Wolf:ET instead :)
