For all you people asking "Does this count?" for your resource questions, I have a simple question to ask in turn. Does your game have to include something, ANYTHING, in the graphics/audio folders that has to be downloaded from you?
If you said yes, then that's not RTP-only. That's editing, customization, whatever you want to call it. We're going by exactly what's given to you from the start, where another person can copy only the data folder (script data not included) and be able to play your game perfectly. This means no pictures, no re-colors (unless it's in-game tinting, which is actually just eventing rather than editing resources), no extra scripts, no nothin'. That's the RTP challenge, to use only the RTP defaults.
