Yeah, I'm not having that kind of shenanigans going down on TSG-R. The races on the channel are all or nothing. None of this "part one is here, the rest is over here." As for exposure for the racers, every time each racer is asked if they want anything plugged in the description.
I'm sorry, but RPG's start to finish just aren't going to make for races for this channel. If you want to do an RPG, then come up with a short single segment challenge. A specific example I hthought of is a race through the Pit of 100 Trials in one of the Paper Mario games. There are interesting challenges to be found in there, but start to finish, honestly, is pretty boring when most of the game will be menu navigation and mindless grinding.
