Considering that you can build directly in the air, the whole issue is rather moot, but I keep stumbling into replicas of tall structures in Second Life, as well as more fictional towers. There are more than a few tower replicas not built to scale, which I mostly won’t be detailing here, since quite a few of them are built to less than 1:2 scale, and as such aren’t very interesting, even if they are very tall.
Eiffel Tower was the first structure of this type built in physical space, and is supposed to be 324 meters tall. However, this replica is only 154 meters tall, and isn’t particularly detailed. It is worthy of note though because it is the only one in which the builder thought to include a few sets of kiss poseballs on the upper platform.
Tokyo Tower is built exactly to scale, and is 333 meters tall. This is one of the most detailed replicas I’ve seen in Second Life.
Metaverse Broadcasting built a replica of the Empire State building for their headquarters, and while it is more or less realistic, it is only about 383 meters tall, when the original Empire State is almost 449.
The Ostankino Tower in Russian Worldware is built exactly to scale with it’s material counterpart, and is quite likely to vanish soon because the sim is apparently up for sale. It is 563 meters tall.
However, the list wouldn’t be complete without the tallest original towers built in Second Life. The Laurentia tower is one of the prettiest and one of the tallest at 1500m, and also happens to have the distinction of being the only tower of this type with a real staircase inside, all the way from top to bottom. It is, however, still not the tallest one.
All known standing structures dwarfed by the SLNews tower, which is 2000 meters tall. There is a platform at the old build limit, at 760 meters, but apparently it was extended all the way to 2000, where the the sim ran out of primitives.
Don’t ask me what’s the point, but I suppose having other people talk about them is good enough. 🙂
