I don't get why this game got fire while trash games like PUBG get high praise

I just think people expect different things from different types of games, and also different things from different developers.

If I buy the next elder scrolls game I'm expecting a large immersive open world, radiating quests, cave diving, and most importantly the ability and tools to easily mod the game. I'm not expecting a great story, well-developed characters, etc. If they put out a semi-open world game with no modding tools I guarantee the outrage from fans would dwarf what we saw with ME:A, no matter how good the rest of the game was.

For Bioware, people don't expect a great open world, level design, etc. They expect good characters, a good story, good role-playing, things along those lines. As has been seen in the many threads about this game, a lot of people feel the game failed at what was supposed to be its bread and butter, and ultimately the pros didn't outweigh the cons. For me personally, if I'm saying the combat was the best part of the game, and it's a Bioware game, odds are I'm not going to play the game again.

Did people have any expectations from this PUBG game? It's a lot easier to enjoy something if you go in with no expectations.

Your brand can be a gift and a curse at times. You can sell a lot of games just off just your brand alone, but it's also a bar that people expect you to live up to, and it's usually higher than bars for others.
