ESO is a terrible mmo wearing the skin of elder scrolls. it has the superficial appearance of skyrim in terms of gameplay but its still mmoshit. you have a hotbar with a few skills, can swap the skills based on the weapon you have but you still have to spam LMB to attack light/heavy.
seriously, do not bother with the game, its like Elder Scrolls: Bored Housewife edition. its for people with nothing better to do, who desperately feel like they need to exist in a version of tamriel 24/7, no matter how terrible and uninspired. The writing is bad fanfiction tier, the game is janky and dated, the graphics are terrible, the micro-transactions are everywhere. seriously, do not touch this game. it is the counterpart to fallout 76.
All that needs to be said about ESO really is this: in ESO, lootboxes are canon and new lore is regularly made up for store items(such as pic rel) and cited in ESO lore discussions. Not to mention they invented a literal Mary Sue of a daedric prince simply for more content only to retcon her one expansion later by sending her to the literal and newly invented Shadow Realm(unrelated to the newly added third moon, yes really they added a moon to justify DLC).
