I saw this rng defeat brock
it was pretty interesting
the guy who leads you to the gym if you try to leave town was a big help
I think you could progress far, possibly even beat the game with RNG input provided that you let it run for a long time at a high speed and that you dealt with a few issues like money and limited safari zone steps.
I think all these runs would be more interesting with unlimited money. It wouldn't break the game or anything, because few of the items would be put to sensible uses anyway. It would add some extra happening though, with interesting pokémart adventures.
