I remember running across a free RPG on the internet several years ago. Unfortunately, the only thing I can remember about it is some vague things from the example of play.
I remember one of the examples had a world with a bunch of islands, and each island corresponded to a giant, and the islands would move about to represent changing relationships between the giants.
I also remember something abour a space-opera ish setting in the solar system.
I bring it up because I just got Universalis, and it reminds me of that system. Maybe it's a dim recollection of an early version?
I know it's a long shot, but if this sounds familiar to anyone, I'd really appreciate hearing about it, if only to verify that I'm not going mad :)

I think I found it. In case anyone else is curious, the thing I was thinking of is Giants of the Deep, which was created by Loren Miller, using Matrix Games (from Hamster Press).

Ah, is this available on the 'net? If so, I'd appreciate the URL, either here or by PM. I'm always interested in things which emereg from the Matrix games stable.

I haven't been able to find it - I only found some references to it in other stuff. I found a reference to it on Hamsters site
http://www.io.com/~hamster/links.htm
but none of the pages exist anymore.

This is why we have archive.org =)

...is the most recent (late 2001) snapshot of the page from what you linked above. The other GOTD page seems to be the exact same thing.
