>>51356441The idea that random encounters are a "problem" to be solved in RPGs is a purely subjective position.
What matters is what your game is intending to do. If your focus is on a traditional dungeon crawl experience, you'll want random encounters. If you want more realism or immersion like an open world game, you'll want overworld encounters. There's merits to both.
Random encounters
>level design can focus on appropriately challenging the player with various kinds of puzzles or mazes>preparing your resources and balancing them against attrition of enemies can be engaging>more possible variety of enemies since they don't have to be incorporated into the world>dangerous areas shouldn't necessarily allow the player to pick their fightsOverworld encounters
>immersive because you can physically see monsters walking around in the world>fights can be more easily avoided if desired>level design lends itself to sprawling open areas but this isn't a givenPokemon probably lends itself more to overworld encounters in theory since bringing the world of Pokemon to life is largely appealing for many. But again it's down to preference
