Well, most still are korean grinders, eusheusheushe.

You can notice it on the lack of design. The combat that is the same in every single one of them. For instance; level 2 skill = dual slash, and they give it a fancy name on each game, but it's still the exact same skill. The interface looks so outdated and similar in each. You end up fighting the same monsters with rarely anything different to them, or they give you the same monster as boss, name it elite and make it look bigger.

It's not a matter of being an Asian grinder, it's just a straight on fact that people draw similarities between them and give them a tag.
