Ways to Make Your Let’s Go Pikachu & Eevee Playthrough More Difficult
Restrict the Way You Swap Pokemon
This is a combination of self-imposed rules that you can use to make Pokemon Let’s Go Pikachu & Eevee more difficult, all based around restricting how you can swap, move, and heal your Pokemon.
Pokemon Let’s Go allows you to access your Pokemon box whenever you want. Pretend that doesn’t exist if you want to make the game harder. Only allow yourself to swap Pokemon when you’re in the safety of a town or Pokemon Center.
On top of that, you can also keep a set order to your Pokemon. In other words, you have to use your Pokemon in the order that you have them in your party. If you combine this with permanent death, it makes battles way more scary.
A caveat could be allowing yourself to switch to a Pokemon of your choosing only after defeating a Pokemon, that you can at least not leave a party member to die after a close fight.
