General Tips Edit
Make sure to visit the route to the west of Viridian City early on, and make sure to not advance past the first patch of grass if you don't want to fight your rival.
Always carry something to cure the poison status, if possible. When in Viridian forest, beware of Weedles.
Remember you can't evolve pokemon that aren't part of the original 151 ones, so forget about Kingdra or Steelix.
it's reccomended to play with a dupes clause if you don't mind fighting a few Pokemon until you find one that you don't have, as Pokemon tend to repeat a lot. If you don't have the time or patience to do it, ignore the dupes clause.
