Seems there was this videogame much like the computer version of Civilization where each player built up megacities (a la Judge Dredd); you'd sort and divvy the resources, work on growth here and there, etc.. and could try aggressive corporate take-overs of surrounding megacities (IE: Other folks' stuff). Someone was talking with me about if this could be adapted to online text-only MU* gaming for a while, and I thought I might as well check it out on my own.
So, I went into the cities. Yes, the "cities" that were part of the game were a thing one could visit that were just -teaming- with folks. The entry into the cities was charming since it was kind've like the start of Star Wars (Episode 4) where you first just see a bit of it and then realize that little bit is just a tip of a spire of a far -far- larger thing. It was much like "House" in Tad Williams' Otherland.
Anyway, so I was zipping around down on street-level with the folks who lived in the cities, who apparently were other players. For some reason I was dressed like the 8th Doctor Who (the one from that one movie) and I was on some sort've floating chair. It was a high-backed Victorian affair (like you'd expect for the 8th Doctor), but it hovered like Rygel's (from FarScape's) throne. As per usual for myself and hovering, it was like a Newtonian physics demonstration on ice so I constantly had to grab onto things to slingshot around them if I had picked up too big of a head of steam.
At one point I was quite positive I saw liatarded's picture on a house (seems most of the housing was a terrace type affair and folks tended to put what amounted to Icon/Avatar/User Pictures as the front wall/window in twelve-foot by twelve-foot prints), but I was having horrid luck getting up to the terrace level that the house/apartment/condo was on.
