You can also get rid of tall grass by using Cut. It might be worth it to use it instead of wasting a repel sometimes. On the other hand, with inevitable encounters, you could take advantage of them by catching the Pokémon you encounter to help you get the Rainbow Pass.
Don't forget about the seven hidden Rare Candies at Cerulean City, Route 6, Route 9, Route 17, Route 12, Pokémon Mansion and Cape Brink.
I hope somebody decides to do HGSS too...

Well, actually there are five: another one hidden in Mount Moon and a hidden one in the Pokémon Mansion. Still, maybe it would be simpler to just capture Wigglytuff.

I think at best a 100% run involving collecting all the star bits alone would be justification enough. Sure, you could get to max level easy enough, but is it really required? You could certainly overkill with that much BP, possibly slaughtering Bowser in a quick hurry, but I think it might be more impressive doing that without such an abundance of badge equipping power. A lot of Star Pieces are actually very well hidden and getting all of them in interesting ways can spice up the movie a bit, though that would be hilariously difficult given the style of the overworld, possibly.
Either way, this TAS? I would watch it. Possibly masturbate to it too.
Um... What Star Bits? And I really don't think you should use that fourth-to-last word here; there might be preteens around.
