TL;DR: It feels like a cheap mmo in a lot of areas. It features: expensive cash shop, lots of paywalls, clunky combat, and inventory management problems....like lots of them.
I was really excited finally getting into this game after all these years. I came with some expectations, but knew TESO was different than previous Elder Scrolls games.
First of all, the game feels like a cheap MMO in many areas.
For instnace, you have a lot of mechanics at your disposal to block/dodge, etc. But somehow enemies still manage to hit you when you simply move away from a charged attack (I attempted about 2 seconds worth of sprint).
Combat feels like skyrim combat for first few levels of the game, but then when you get some skills it feels like there has a been some really low budget MMO combat slapped onto it. Animations look bad (sped up versions of basic attacks ones), everything feels clunky and main progression appears to be dumbed down and even more linear than it was in skyrim.
Secondly, you'll find a lot of features that were in every previous game locked behind paywalls (expensive ones). Let's take inventory for example. You get a set amount of SLOTS (not weight)... FINE, they have to manage the data somehow, but they did not address any of the inventory-devouring features previous games had. For instance, If you have 2 identical stackable items: 1 stolen and 1 not, they each take up a slot. Some identical looking (name, text and everything) potions don't stack. Your options: the most prevalent option is premium, because it gets you material storage (and that's what really takes up the space). The other option is getting inventory slots (you have no chance to get too many as a new player, and you kinda need them fairly early on).
Finally, It's not all bad.... The game still has a large world and an exploration element to it (learning skills works similar way it did in previous games, so you can actually learn guild/world and other skills by exploring/doing quests), but clunky combat and bad monetization are usually deal-breakers for me.
EDIT: Came back to reduce the score even further, because apparently the game publishers/developers didn't find uninstaller important enough to fix in last 4 years. While clearing space on my game disk I noticed that ESO is still sitting there all 69GB of it.... I tried installing and uninstalling it again and sure enough, it got new updates, increased in size and none of it got removed by uninstaller. This is a problem that was reported back in 2015 and it wasn't fixed until 2019....
