Rules:
1. Only my starter in battle
2. No items in battle, except held items
3. No glitches, exploits, or save states
4. No movepool evasion-boosting moves before level 100*

Rule details:
-- I make no attempt to have the exact same rule details between generations.
-- I am allowed to manipulate my starter
-- I play the game at 4x game speed
-- For fair comparisons my Pokemon have perfect (or near perfect) DVs / IVs
-- I am allowed to catch HM users - I can use all field moves
-- Evasion boosting is allowed if the move is not obtained from the Pokemon’s movepool. For example, using Mimic or Mirror Move to boost evasion is allowed.
-- Surge's trash-can-puzzle is automatically solved
-- The bike is allowed in gen1 & 4, banned in gen2, and allowed only to bypass terrain in gen3
-- Saving between league members is allowed
-- I can pause the game and timer to take breaks
-- Items obtained with the ability Pickup can only be used if the starter obtained them
-- The footage is sped up & slowed down to match the pace of my narration

These Rule details apply only to generation 1:
-- All battle-mechanic glitches are allowed (glitches that occur outside of battle are banned)
-- In generation 1, I'm allowed to skip Marowak with the Poke Doll

If you didn’t read these rules and left a comment. Thanks for helping with the algorithm.
