Until now many people would use free shards to play without cost and then Endless Journey was introduced in 2022. This allows you to play Ultima Online for free every month with most features unlocked! And the best part, this is all possible on the real Ultima Online shards like Atlantic, Great Lakes, Pacific and more. Visit your EAGames account and create a Ultima Online account through this portal: https://accounts.eamythic.com/
The classic and enhanced clients for Ultima Online can be downloaded from the official UO website: https://uo.com/client-download/. It is also possible to run them on a Mac by changing your envirment or downloading some apps.
