Um no... I call then tabletop RPGs because that's just what they are called. It's just terminology, like the World Series is called the "World Series" and the winners are called "World Champions" despite not actually involving any team outside The US or Canada.

Anyways, you're trying to literally translate a non-English terminology and directly compare it to English terminology. It doesn't work that way.

I played Settlers of Catan and that's a "board game."
