unreal engine - free?

[3drocker]

hello,

i'm a newbie and so I wonder if anyone knows of an engine that has the same capability as unreal engine. Is there a free one?

Which version ? For what needs ?

You have Quake 3 fully open sourced, I like the ioquake3 fork wich is easily compilable with current compilers :

A bunch of infos and links to other free engines :
