>making a TM that can only be used for two Pokémon, with

Gen I was weird in general.
TMs clearly weren't made with an attempt to be competitively relevant in mind, so Gen I TMs are full of esoteric and weird moves like Softboiled.

Because.

Don't meme on Water Gun though, that shit's surprisingly useful for Mt Moon on a Rattata or Nidoran or whatever.

Or Gyarados if you want to save Bubblebeam and you're still far away from the Safari.

This just goes to show how incompetent GF is at making games, if that needed any more confirmation

Sorry, moves like Softboiled, which despite appearing to be made just for Chansey, they seemingly decided was too strong for all Chansey to just learn by themselves, and thus forced you to make the choice to only ever have one Chansey learn it.

This is literally the same thing as Relic Song and other kinds of exclusive moves you have to learn through special means. It's just that in gen 1, the only "special mean" they had was TMs.

Perhaps, but it makes you wonder why they didn't just give it to Chansey as a level-up move and make the TM something else.
