A good example is Elex. It's got a good world/story, fun factions, it looks pretty good, exploration is interesting and fun. But the combat is horrific. Balancing is terrible. You'll find high level enemies right next to low level ones. The actual gameplay is so bad.

And you'll see it repeated over and over on the reviews on the steam page.

Some people claim it gets better if you stick with it, and I did because I was playing it over a holiday. My experience was they're wrong, it never gets better.
