Ultima Online: The Second Age was the first expansion for the Ultima Online MMORPG. It added several features to the game, including a new region called the Lost Lands, new creatures, and support for player-built cities. It added runebooks which could be used to hold recall runes; the player could add runes marked with the mark spell into them rather than carrying individual runes. They were not blessed, however, meaning they could be looted or stolen from a player. It also added something called young player status, at which time it eliminated the original resurrection option where one could opt to instantly resurrect but with penalties.
Critical reaction to the game was mixed. The Second Age was given the "Online Role-Playing Game of the Year" award at the 1999 Interactive Achievement Awards. Many reviews criticized The Second Age for not expanding the game enough, especially since gamers were anticipating the 3D MMORPGs EverQuest and Asheron's Call.
In 2007, Ultima Online: The Second Age was re-released as a player run shard. While not supported by Electronic Arts, the original gameplay of this expansion is re-created through use of third party programs such as RunUO and Razor.
