Speaking of nostalgia, and for the life of me I can't find further discussion of it here in the forums, Megiddo started a project that would, in my opinion, and even at the time, have blown SpaceBuild away.
http://forums.ulyssesmod.net/index.php/topic,184.0.html is the only discussion I can find. (and even it links to a LONG dead link)
I can't remember the name of the project, but basically, if a map had spheres/other shapes in it, a player could WALK AROUND THEM in 3d space.
The map did require special internals. If more than one 'planet', you could break gravity, free float, and then land on the other 'planet' and walk 'upright'.
It was slightly buggy, but was great for beta idea/code/implementation.
Last I remember, it died, partially due to Zyklus (Stickly Man's older brother (did ya know he had an older brother that used to hang with Megiddo?)) not making more maps for it.
Only partially. Megiddo has always been one to start awesome projects he barely has time for.
Now that I think of it, I'm amazed he's even married.
Wait, I'm amazed he found time to date or to propose.
