I thought OGRE was older, too. But maybe just 2d.
Also the footer copyright on this page says 2002.

Not sure what the launch in 2005 entailed, probably a rebranding and freshening up to make it seem more serious and appealing to developers, but it was already one of the better 3d frameworks around at the time. I was able to extend it to support LUA scripting in my game engine, was well abstracted and really nice to work with.
Had the original board game back in the day.
The work in progress Cyberpunk module for GURPS was confiscated and believed to be a "handbook for hackers".
The most Hackernews comment I've ever read is someone getting defensive about the distinction.
