Even without egg moves, the first generation still manages to have some moveset conflicts! Here is the list for pure RBY in its entirety:
Almost all of the combinations arise from differences in learnsets between members of an evolutionary line, causing conflicts in evolution timing - one move wants evolution too early, and the other wants to wait too long before evolving.
The Tackle/Growl clash for the Eevee family comes from the learnset change from RB to Y so the rival could use Eevee as a starter. There are three different games in which you can get an Eevee and all of them have different starting moves (and no way to regain Tackle/Growl):
If the Stadium 2 relearner were introduced into the equation, these combinations would disappear, but I believe this would qualify as a Gen 2 game.
Speaking of tradebacks, I also have the list of moveset conflicts if all Generation 2 games were allowed for teaching moves. It's derived from the full Generation 2 list below.
The GSC illegal moveset combination list far exceeds the character limit for a single post, so I had to break it out into four posts:
Part 1
Part 2
Part 3
Part 4
The primary clashes here are incompatible egg moves, event moves with egg moves and other event moves, and irrecoverable GSC-introduced moves with RBY-only TMs and a few RBY-only level-up moves.
Unlike with the previous illegal moveset threads, which were workshops, the lists here are complete, and the only issues here are potential mistakes I might have made.
