>>3797765Tbh, its worth a playtrough for sure.
RPG history wise it started some trends that were eagerly picked up by the mainstream afterwards.
Fast travel, quest markers, level-scaling, linear quest design with few choices. Many of these may not have been introduced by Oblivion, but its success made them go mainstream.
Other things, like radiant AI, are worth experiencing. Whether you thing it endearing or immersion breaking and ridiculous depends on you.
Some of its lauded questlines, like TG or DB, follow the same linear design, with very few exceptions.
Personally I feel similarly about Skyrim, but it did have a more appealing art-direction and much greater mod support.
Morrowind is the game that made TES lore special, and none of the other games recapture that. But as a game it has plenty of issues too.
