Re: Neverdaunt 8bit
Since Jeff M (I think) seemed to have trouble describing it, I'd like to throw a suggestion out there:

A Garry's Mod-style MMO with primitive graphics. (there's more to it than that, but this should give you an idea)

It's a fun little sandbox to muck around in, I never got into it enough to actually bother trying to capture my own territory or anything. Whatever I build would have been made in the public cells, and was usually torn apart within an hour or two.
