Re: Interest check to actual RTJ rates?
There are other aspects too. I stated interest in a 5th ed DnD game, but there were two problems that prevented my rtj.
First, the GM didn't link his when he set it, nor did he state what the name was or anything else. I had to use the search function on his name to find the game (thank goodness he had only the one game).
Second, I got held up with work and real life, so when I did eventually find the game, it was no longer accepting players.
By all appearances, it was first come, first serve, on that front too, making any rtj from pointless.
Also, generally speaking the interest check will have just a basic idea, but the rtj and info thread usually has more, and players may like the basic idea but be unhappy with where you went with it.
