Back 4 Blood, opinions
Honestly surprised how much "the original developers behind Left 4 Dead" don't know about how Left 4 Dead works and what makes it good - I'm not even through Act 1 and the pace is horrible, the levels are easy to get lost in, the AI is dumb, "mutants" are spongy, the guns feel horrible, etc etc

But the single biggest crime, is that it's a zombie shooter where shooting zombies aren't satisfying. In Left 4 Dead 2 your shots would tear off parts, gore going everywhere, but in Back 4 Blood it's just, meh, they kinda fall down limp after a few shots
Playing Back 4 Blood just makes me want to fire up Left 4 Dead 2 again.
