No problem

I'm so used to non-native English speakers being as good as or better than native speakers (And trust me, you're well on the way - your English is great

) that I tend not to make as much allowance as I should.
I think what games companies usually consider the difference is what is the most important part of the game: in an 'Action-RPG' the main emphasis is on combat over and above anything else whereas in a straight RPG the most important part is the characters and the story.
It's why games like The Witcher and the Baldur's Gate series get classified as straight RPGs despite having a lot of fighting in them. The fighting is not the point of the game. In an 'Action-RPG' it is.
