Nice, is there a way to get them to change RPG Dragon Knight to RPG Dragon Knight 2.0 as Dragon Knight is not mine and is another game altogether?
If the only difference between "RPG Dragon Knight" and "RPG Dragon Knight 2.0" is "2.0" then there is no meaningful difference. They may not be the same game but they clearly share the same name.
I took the liberty to look it up at uspto.gov and discovered a few variations on the terms but I have good news for you,
Dragon Knight is actually available. The trademark that was filed appears to have been abandoned before it was finalized:

I would suggest you grab that trademark.
Also, Dragon Knights is also available, that guy actually completed his trademark process then let it expire 10 years later:
