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 and cited in ESO lore discussions alongside trans-crocodilian Argonians and Breton druids pleasuring their wolves. Not to mention they invented a literal Mary Sue of a daedric prince simply for more content only to retroactively retcon her one expansion later with the players sending her into the literal shadow realm.
