I mean, if you like RNG, play Pokemon. Lots of run-killing RNG there.
Megaman battle chip challenge 99 percent of the game is you sitting there just hope for good rng
To answer a previous question, YES, Kirby's Dream Land has a decent amount of RNG, especially in the boss fights. It can actually kill a run if you get a bad Kracko, or Wispy, etc.
Poppy can choose to add 15 seconds to your run by delaying a jump before throwing its last bomb. It's frustrating.
But also awesome. :)
Sorry, I just saw this. Yes, Kirby's Dream Land can almost exclusively be RNG once you get the route down. Kracko (boss from stage 4) is fought twice during the run and can take around 20 seconds to upwards of a minute depending on RNG. Dedede is a similar situation. The game definitely rewards grinding and consistency.
I have a slew of NES games, as well as GB, GBC, GBA games on my profile, that are usually shorter runs and such. You might be able to find something that strikes your interest in there.
