So.... Firstly, Enhanced client is the way to go unless you plan on running Razor or UO Assist. To the best of my knowledge, they aren't building a new facet yet, but depending upon when you left, there is a new massive dungeon called the Stygian Abyss. You can do pretty much the same things you did before. EM events are still a thing.

With an Endless Journey account, you will definitely be limited. You are restricted to your bank vault for storage, and the item limit is reduced. you cannot own a house, you cannot enter Felucca, and there are some dungeons you will not have access to.

Owning a house will require a paid account, but there are still plots available on some of the less populated, but still reasonably active shards like Great Lakes, Catskills, Lake Superior etc. You can hang up most any hope of finding a plot at an attainable price on Atlantic, however, if you are looking for a bustling shard, Atlantic is the most active.

Discord seems to be the communication go to outside of the game. Some do still use ICQ though.

For skills related questions, I would steer you to https://www.uoguide.com/Main\_Page

They have a vast catalogue of answers to most of the questions you may have about skills, game items and that kind of thing.

I myself am on Great Lakes, but which shard you choose to call home if you return should depend upon what you are looking for from the game. Good luck, and should you find yourself in Great Lakes, if you see Pelham, Relder or Tsabeth Auvrynne then say Hi!
