Some things are improved by realism, sure. But most things, especially when it comes to games, are probably better because they're not realistic. Case in point: Pokémon, which would be way different (read: way worse) if its society and creatures worked more like they do in the real world.

Here's a silly but entertaining video by Animation Domination High-Def which looks at what a more 'scientifically accurate' Pokémon world would be like. It's...not really the type of game I want to play, personally, but it's still kind of fun to think about.
