I own Enderal on Steam and have yet to finish my first full playthrough, but that's clocked in at about +100 hours.
Enderal and is not Skyrim. Enderal is it's own game, and, in my opinion, that game gives Skyrim a run for it's money if not blows it out of the water.
To elaborate on why I give this four stars instead of five: Despite it having several patches and being an entirely different game, Enderal does contain some of the jank that Skyrim has. Combat is slightly better through some of the tweaks and additions made by SureAI, but it's still Skyrim combat. There's also a few "meh" writing moments in the main story and side quests. Sometimes NPC and player dialogue leave a bit to be desired. Voice acting is fine for the most part, but many of the secondary characters in the story are solid. Some creature/enemy models/meshes are also "meh" and you feel compelled to "de-Skyrim-ify" them with additional mods. It's also a shame regarding the limited scope of the game, as there's moments where it feels like opportunities were missed out on for more content.
Aside from those few things, Enderal is a vastly better experience than Skyrim. The progression system and skill trees feel, while still tied to Skyrim's boring combat and crafting systems, much more thought out. Exploration and progression are actually tied together. Your character can eventually gain a class, which is incredibly refreshing that you can actually somewhat role play. While leveled areas in the world might seem odd to the casual Skyrim player, they make sense in the interesting world SureAI created. Magic, while still OP, actually has a bit more to it gameplay and lore-wise compared to Skyrim.
In short, Enderal is a good game, not a good mod. The most disappointing thing about this game is that there's an end, and you wish the end wouldn't come as quickly as you'd like, so you will likely find yourself really trying to squeeze out 80-100 hours to delay the end and explore the world.
