A role play game game
Sure!
Not sure why I feel the need to defend myself, but:
"
RPG" can be used as a category, thus the category was followed by the fact that I wanted you to know that this is indeed a game, and not a book - or something else - that this genre can be associated with.
If I posted "I made a short RPG" as a title, you may think that I was talking about something that has to do with Blockland itself, seeing as this is the Blockland Forums. People have built Blockland RPGs, which would be titled:
"I made a short RPG build" or something along those lines, indicating that the person/people made a build, and evented it to resemble some sort of Role-Play setup.
...Just thought I'd clarify.
