The server is based on Sigil and the planes. Instead of fae'rune or any other prime world you travel across the planes and do most of your rp in sigil itself. The city itself is huge... 3-4 times larger then BG with 6-7 large areas. Its also very confusing for first time players. Its difficult to navigate as well as the city is A-symmetrical and not laid out in any logical fashion.
Most of the rp goes on in an area aptly named, The great bazaar. They don't have an auction system like BG but rather use a very advanced system of player run merchants. There are often several such player merchants set up there with dozens of chests and sometimes thousands of items for sale. Loot is somewhat more generous then BG but it also scales to ones lv so low lv characters will find low end stuff most of the time, often merely scrolls... which is good if you are a wizard but not that great otherwise.
It is much easier to solo then BG but grouping gives much greater benefits. Lving is much faster then BG but due to the difficulty of finding groups and the much lower amount of grinding going on this is not that great of an advantage as it may seem. Also while the low and mid lv areas can be soloed the high lv areas require a group and as said groups are very hard to find as they have no scry window and only two or three people grind at any one time.
They have much fewer dms then BG and thus much fewer events. Most people spend all their time on rp and almost none on pvm or pvp. They do have the custom item appearance changer which is the feature i am there for primarily. They use the standard crafting system using gems, essences, and powers to enchant stuff. Enchanters on that server can make some obscene amounts of money enchanting stuff for people.
Overall i find BG to be the better server. Its bigger, has more people, and more stuff happening at any one time. Its also more kind to new players. Sigil is not a bad server but BG is, for me at least... the better server. Hopefully this is sufficient for those who were curious. Soon as i figure out how to upload my custom armor file i shall be back permanently. Wish me luck.
Cheers!
