Tamriel is an interesting place and I always want to explore a new area (or revisit an old one) in that world as well as the culture and customs of the people who live there. This has always been the exciting thing a new Elder Scrolls game even if I fully admit that I didn't like IV or V that much. An MMO with a regular release of new expansions is a good means of exploring this instead of waiting many years between mainline entries even if these DLCs will never be as deep as a full game. In this regard, I think Orsinium is quite successful. The Orsimer were never an Elder Scrolls race I was particularly interested in but I've come out the other side of this expansion feeling differently. I might play as an Orc in VI if it ever comes out. The story is pretty good even if the basic plot is fairly familiar with stuff you've seen in the base game. Kingmaking and an evil cult. There's so many evil cults in Elder Scrolls Online. Still, I enjoyed playing through and was interested in the characters. The new zone, Wrothgar is fun to explore and I liked the city of Orsinium itself. The base game cities could be pretty boring so the DLCs have stepped up in that regard. There isn't anything new with the gameplay but I did enjoy the solo Maelstrom Arena. It's nice to have solo content that's actually pretty challenging and it gave you new weapons that are still very useful for builds 8 years later. Definitely worth playing through if you enjoy the main game.
