Re: Favorite Evolution Method?
I like level up evolutions as well. It's nice having to work for something and having a goal level to aim for.
If a Pokemon evolves by stone I usually won't evolve it because I don't like wasting items that are hard to get. (In games where you can buy/find stones easily, it obviously doesn't matter, but then I have to make sure the Pokemon has all the moves I want it to have as well.)
Happiness would be my second favourite. I agree with Not Safe For Adults, it's fun not knowing when it will happen. Every level-up is exciting!
