Ultima Online is more of an Elder Scrolls Online than ESO is.
It’s an average MMO in an ES skin, instead of an ES game made into an MMO. Can’t say too much because of NDA, but many major components of classic ES games were removed, when they very easily could have worked. You are much more restricted in your choices than you should be thanks to their class system. (I think I can say that because on the website it spells out their class system)
And for those that say “You need to be restricted in this type of gaem omg cuz it must be like WoW and hav classes!!!” I point you to the aforementioned UO (still around), to Asherons Call (which was highly successful back in the day), and to SWG (while it was freeform, the only period it was worth playing in).
Also, somehow the game felt like it was on rails. I don’t know how they managed that in an MMO.
Was disappointed. Horribly.
Edit: Then again, they only let us play 2 and a half days at a time, and wanted us to test specific features in those 2 days. Not really much time to get lost in the game and really get to the nitty gritty. But for the 4 days total I played, I was underwhelmed the entire time/
